I'll use a list originally made for Chinese plane exports. But there's enough interesting data here so it can be applied to Russian prospects as well.
I thought I'd make a detailed list of countries that might see some exports of Chinese fighter jets (no UAVs in this analysis though) in the next decade or so.
To start it off, some elimination. Certain countries are simply unlikely to even consider buying Chinese. That's basically the west-aligned countries.
Also, certain countries don't have even jet trainers in their air forces (if they can afford an air force at all). So those would be off the list as well.
Of course, very poor countries aren't even a possibility. So any country with GDP of less than $20 billion per year isn't considered.
When both of those are excluded, what we're left with is:
Cuba
Has soviet planes, old, but in reality they seem to have given up on having an active air force. Unsure if politically US pressure may be too great for China to have any chance of selling high tech arms there. I'd rate it as a no for chinese jets.
Colombia
has us, brazilian and israel jets. Seems pretty much western leaning. I'd say no for chinese jets.
Venezuela
Has russian jets which, especially since the country is bankrupt, will likely be held onto for over a decade more. Has some F16s which could need replacement. And two dozen chinese K8 trainers. Politically, Chinese stuff might have a good chance. And some planes are only getting older. But given the lack of money I don't see anything but perhaps a dozen or two cheap trainers or at best combat L15 jets as a possibility here. Perhaps during the 2030s there might be some more expensive plane purchases but that's beyond the scope of this analysis.
Ecuador
South african and us, european stuff. Under the US sphere, I'd say. a no go.
Peru
Has soviet and french m2000. In theory this might go, though I'm sure the US would cry foul and threaten sanctions. Doubtful that anything other than jet trainers, perhaps a dozen would go through. If even that.
Uruguay
has some chinese transports, but has only western trainers and light attack planes. I guess possible, but again, unlikely. And if a sale does happen, L15 class plane is probably the most that can be sold. Probably not even a dozen.
Argentina
Has no air force, though it isn't a poor country. but the military is one of the last things they're spending money on. And they seem to be western leaning more than anything else. Could go either way i guess, depending on new governments in the future, so anything from a L15 to even JF-17 is possible. Theoretically even J-10. But it's too hard to call. They could just as easily (or even more likely) go western and/or decide to stick to very low numbers. Perhaps be content with second hand f16s or just a dozen Gripens or Korean T50s or whatever.
Serbia
Has a dozen refurbished mig29. Has no money so will likely stick to those up to 2030. Perhaps some chinese jet trainers are possible. maybe up to half a dozen? But yak130 may be even more likely, due to political ties.
tunisia -
only western so far, US influence is pretty strong. I'd say a no go.
Algeria
buying russian currently. su30 and new mig29 and rumors say maybe even su32. Maybe some trainers left for china? Though russian ties are stronger so I'd say unlikely purchase here.
Uganda
Has some mig21, 8 su30. I guess they could go for several JF17. And/or perhaps more likely chinese trainers. Perhaps even a dozen? Theoretically Russia might stop the purchase via engines but then again, I don't see them talking Uganda into getting mig29 so they might not.
Cambodia
Has some L39. has some Y12, so precedent for chinese is there. Could in theory get chinese trainers.
Laos
20 yak130 on order. Unlikely they'll need anything else and expensive.
Senegal
4 L39 on order. some russian helos, some european planes. Again unlikely they'll expand in the next decade.
Zambia
has some mig21, may not fly. has chinese transports. has L15. Possible that a few more L15 will be bought. Perhaps combat L15 will be bought on top of those. Or even half a dozen JF17. who knows.
Yemen
has west and east planes. possibly a few dozen soviet ones. Might enjoy replacement planes but it's politically sensitive stuff. China or Russia don't want to anger Saudis over Yemen. So until there's a regime change in Yemen this may be on hold. If regime change does happen - we may indeed see a dozen trainers and a dozen cheap jets like JF17. But Russia might stall that purchase through the blocked engine sale so they can sell their own planes.
sudan
has russian 29/25. has j7. could be a candidate. Perhaps half a dozen trainers and a dozen JF17 class jets. Not sure Russia would even try to intervene here and stop jf17 sales.
libya
soviet planes two dozen, on paper. May need rebuilding. Could be a race between Russia and China to help them rebuild. Some chances for a dozen trainers and two dozen cheap jets. If there'd be no russian limits on JF17, i'd say china has even some greater chances here.
cameroon.
Has some chinese transports. some russian, some us. has 6 alpha jets. There might be need for half a dozen new trainers, so China may have some chance there.
turkmenistan
Old soviet migs and sukhois 29/25 40 pcs on paper. Could need replacements but Central asia is quite under russian influence. I guess some chance for l15/jf17 or even j10 does exist - but it's small.
azerbaijan
old soviet planes 29/25 25 pcs, 12 l39 trainers. Some replacements are quite likely. Russia prefers Armenia to Azerbaijan, so China might have some room here. Perhaps a dozen trainers and two dozen cheap jet fighters are possible.
congo
6 soviet jet fighters. possibly don't fly. Don't see they'd go for more than some trainers.
syria
100+ fighters on paper. 36 yak130 on order, some mig29M2 on order. might need more, but might have no money. And russian influence is pretty strong. I'd say Chinese sales are not likely. If they do materialize, perhaps combat L15s seem most likely, but not over a dozen or two. I guess jf17 class planes are also possible, but if Russia doesn't block the sale.
uzbekistan
39 mig29, 27 su27, 20 su25. they all might need replacement. but russian influence might lower chinese chances. Even if they do buy chinese, i don't see them not buying russian as well. So only a piece of the cake. again smaller jets and trainers.
belarus.
soviet. 12 su30 on order. has yak130. Strong russian influence. I'd say a no go.
tanzania.
has chinese planes. 5 jl8, 5 j7. Might go for some modernization. but only a few trainer class planes.
myanmar.
has chinese. 10 jf17 on order, su30 on order. jl8 and yak130 on order. They're probably done ordering stuff for the next decade. Maaaybe a small top up order of Jf17 could be expected.
ghana
has 4 k8 trainers. 5 coin planes on order. Possible L15 order, but half a dozen at most.
sri lanka
some j7 and kfir. has chinese stuff. some jl8. They could actually go for a decent buy, if there was no Indian factor and political pressure. half a dozen trainers, perhaps up to a dozen light fighters. But given the India factor - who knows.
ethiopia
has l39 10 pcs, has 25-50 soviet planes. could indeed go for chinese in the next 10 years. Perhaps 6-12 trainers, double that number of light jets? J10 theoretically possible but I'd say unlikely due to cost.
angola
9 czech trainers. soviet helos. 10 su30 on order. a few dozen soviet fighters. Is already ordering russian. though given the large flankers, there may be room for some JF17 or L15 orders. Probably not more than a dozen each.
kenya.
has chinese transport and helos and us transport and euro helos. has 17 f5. Could go Chinese. Maybe a dozen cheap planes?
ukraine
This is an interesting one. I can't see them buying russian, due to internal politics. They might want to buy western but likely have no money. And we've actually seen reluctance to the west arming Ukraine, when it comes to hand me downs. So china MAY have some chances here. But their money situation may be so bad and western pressure so great that again flashy purchases like J10 are unlikely. I could see chinese trainers, though. Not sure about JF17. Hard to assess numbers. A dozen? Several dozen?
kazakhstan
20 su30 on order. a dozen soviet more. has old l39 trainers. Likely done buying fighter jets. Likely will go for yak130. Don't think China will be able to squeeze in.
iraq.
recently got new stuff. f16, t50, l159. perhaps su25 can be replaced? Chinese stuff has been bought before so politically it's not an issue. But other than L15 class planes, a dozen or so, I don't think it's likely.
Vietnam
has a few dozen soviet. 30 su30. has 30 l39. Due to politics with China, i'd say any purchase is unlikely. They will stick to Russia.
Pakistan
JF17 program goes well, though I'd assume China earns less on each JF17 made/assembled in Pakistan for Pakistan than on any export JF17s (which I assume China may get 50% on?) Still, we'll likely see several dozen more JF17s procured.
And heavier jets are quite likely as well. Will those be J10 or even something FC31 related - remains to be seen. A dozen or two before the 2030s seems quite likely to me. And a few dozen trainers likely.
Egypt
A dozen alpha jets. mig29 and rafale order. 200 f16 will need gradual replacement though. has 119 k8 trainers! and l39 trainers. Egypt will need a steady stream of new planes. Russia will definitely try to sell its own. and possibly even stop jf17 sales if the engine can be blocked. I'd say China has good chances of selling trainers in 2030s but not before 2030s, as K8s will likely last. Still, there's a decent chance of either JF17, J10 or even FC31 related planes to be sold. Depends on whether there will be further rafale purchases which could prevent the FC31 idea. Perhaps up to dozens of Jf17 or J10 could be sold though.
bangladesh
36 j7, 8 su30 ordered, 8 mig29., 14 yak130 but 10 k8 and some l39. Seems to be buying both russian and chinese so some JF17 and trainers are possible. Perhaps even 2-3 dozen? Not sure about J10 as money may not be there after Su30 purchases.
Philippines
recently got t50. don't seem to be keen on expanding.
South africa
gripens. western influence is strong. i'd say no go for chinese purchase.
Malaysia
18 su30, 8 hornets, 12 hawk. 12 hawk macchi trainers. Could see them buying Chinese L15 class trainers. perhaps even up to two dozen.
nigeria
12 alpha jets. 9 j7. 3 jf17 on order. 20 jet trainers need replacement. I'd say they'll top up the JF17 order, so another 6-9 planes are quite likely. Perhaps up to two dozen trainer jets could also be bought.
thailand
19 alpha jets. 30 f5. l39 trainers. some t50 ordered. has lots of f16s, gripens
Goes both ways, as it has bought chinese stuff before. And does have planes to replace. China should have a decent chance of taking a piece of the pie. Perhaps selling a few dozen trainers. Perhaps even a few dozen JF17 or J10. If J10, I don't see more than two dozen.
indonesia
5 su27, 11 su30. 15 t50. 24 hawk 200. has chinese uavs. They could go for Chinese. so two dozen L15s and even half a dozen or a dozen J10s might be possible.
russia
Will buy own stuff.
india
Due to politics with China, is a no go for chinese purchases.
Saudi Arabia
Sometimes it's labeled as a potential buyer for FC31 derived plane, as the west allegedly won't sell F35. But frankly, i don't think it's likely. And any other class is likely not needed, and would be procured from the west.
Iran
The big unknown. It all very much depends on international politics. could remain under sanctions for another decade. or Russia and China could sell it LOTS of planes. If they, say, split the buy, I see a need and money to buy perhaps 100-200 planes. So a few dozen trainers and a few dozen J17 or J10 class planes are quite possible. Theoretically even FC31 is possible.
turkey
Will likely be flying the f16s into the 2030s but dozens of them will be 40-ish years old by 2030. and 40ish F4 need urgent replacement. While a lot depends on whether the political leaning away from the west continues, i do believe Turkey will keep away from the west (and west from turkey). So russia and china are obvious choices here. Turkish own aerospace can't produce a fighter jet in the next 10 years.
If we assume Russia and China both have 50-50 chances, perhaps we might see a split buy. So heavier planes from Russia and J-10 buys from china? Perhaps several dozen ? Also, lots of trainers might need replacements. So again some dozens of L15 class planes possible.
Keep in mind, buying something up to 2030 doesn't mean getting planes delivered, but merely signing the contract. So in some of these cases deliveries might take to 2035 or later.
I'll try to sum all this up now:
Without counting Iran and Turkey, as the two big unknowns,
I can sum it up to:
144 to 264 possible JF17 sales (also doesn't count Pakistan orders)
36-96 possible J10 sales
12-24 possible FC31 related sales
24-36 combat L15/ftc2000 sales
228-288 jet trainer sales (L15 and other)
Turkey and Iran would increase those by
72 jet trainers
72 j10s
0 to 48 FC31 related sales
Of course - all of these figures are just theoretical UPPER limits. All those countries may go western, or russian or even decide not to buy as many, due to limited budget.
So... if one thinks that China can get one third of the said market,
then the actual sold/contracted planes list might look like this:
48 to 98 JF17 (excluding Pakistan)
12 to 32 J10
4 to 8 FC31 related
8 to 12 combat L15/ftc2000 sales
76 to 96 jet trainers
And if one ADDS the Turkey and Iran possibility as a 100% chance (since we already excluded the west and already split the buy with the Russia) those might change to:
48 to 98 JF17 (excluding Pakistan)
84 to 104 J10
4 to 56 FC31 related
8 to 12 combat L15/ftc2000 sales
148 to 168 jet trainers
Of course, as all this is conjecture - China might end up selling more or less than that number. But even so, at least a few hundred jet aircraft does seem like a likely minimum to be exported by 2030.
****
Now to get back to my post - applying this to Russia could, very roughly speaking, yield that one third of the market (without Turkey and Iran split buy) so that's also
48 to 98 JF17 class planes
12 to 32 J10 class planes
4 to 8 FC31 class plane
The cheap/trainer class plane I did not count.
Without Turkey and Iran, that's basically poor prospects.
The countries that might buy JF17 class plane will almost definitely not go for a stealthy next gen fighter. They simply have no money for that.
Countries that might buy J10 class planes might buy stealthy next gens though as Russian cost of work is likely less than Chinese one, so a stealthy next gen might not be that much more expensive than a J10C class plane. So some of those 12 to 32 sold plane prospects might indeed stretch a bit more and go for a pricier but more potent russian plane.
Of course, all 4 to 8 FC31 class planes are likely to convert to russian next gen stealthy plane.
Still, that's only 40 or so planes sold, in the best case scenario. So Iran and/or Turkey are crucial. Add those two one can get:
84 to 104 J10 plane class required airframes and 4 to 56 FC31 plane class required airframes. For a total of 86 to 160 russian stealthy next gen single engined planes sold abroad, outside russia.
Added issue is other russian products. Some country that might go for the next gen fighter might decide that a Su-35 is enough for them or that it is more cost efficient. Others might prefer Su-57. So Even those 86 to 160 fighters sold might be somewhat of an over reach.
Now... does it even make sense to develop a whole new plane to sell only 80 to 150 fighters abroad? Developing a whole new plane from scratch can easily cost 40 billion $ in the west. Of course, russian costs are much lower, so lets say it can cost just 15 billion. And lets say that lots of Su-57 development (like engine and some stuff) can be leveraged and final development cost is just 10 billion $.
To be competitive with the Chinese, the russians would need to keep their products quite cheap. So instead of selling a stealthy fighter (with all the long term support) for 150 million or 200 million, like the west does, the actual price might have to be closer to 60 or 80 million. Selling 100 of those at 70 million, then, would yield 7 billion. So it might take the whole possible market to cover just the 10 billion that the development cost. And since every plane has its own production cost - those 150 fighters would in reality cost 10 billion for development plus 7+ billion to manufacture them.
In reality, at such prices, it'd take a market of 400 planes sold to simply cover all the expenses. 400 planes * 46 million per plane plus 10 billion development. Is 28 billion. So 400 planes * 70 million retail price to simply get even.
Now, all these money figures are extremely sketch, I am aware of that. It might easily be that only 300 planes are enough to cover the expenses. Or even theoretically that even 250 or 200 are enough. But I do believe that's already pushing it. But EVEN THAT would be more planes needed than there is an attainable market for. And even if someone does break even - that's a horrible investment. Who in their right mind would want to risk a few tens of billions, over more than a decade, probably closer to 2 decades - not to see ANY meaningful return on their investment? There's a zillion better ways to invest money, with less risk, than go into development and marketing a new single engined plane.
Which is why there is ZERO chance such a plane from russia can happen without the Russian state ordering a few hundred planes first, and basically paying for the development of such a plane on their own. So only then the manufacturer could try to risk and keep the price for russian Air force procurement unusually low - counting on export airframes to pick up the slack and actually make them money.
Now - will the Russian government pay for development and procurement (Even at literally manufacture price) of, say, 300 airframes? I'd say unlikely. At least in the next decade or two. there is Su-57 to pay off first, there are existing legacy airframe orders to fulfill, there's the constant talks of Mig31 needing replacement (Which whatever it will be, it most certainly wont be a single engined small-ish plane).
Joining the development and marketing with china might be very prudent. If that's possible. (it might not be). But going at it alone - There's simply no math in there to really justify such a project for Russia for some time to come.
