It's likely to be a MKK. Perhaps a J-11BS but we haven't seen them in this kind of camo before.

The Su35 obviously makes changes to its original skin to meet its mission requirements. Their internal configuration and systems are completely new. What I was trying to say is that the J11B is like the Chinese equivalent of the Su35. Both are upgrades of the Su27 to meet requirements of the twenty first century.
The Russian Sukhois have different variants and the Su-35 has supercruise, and thrust vectoring nozzles, which makes me think comparing it to J-11 is not acurate.
The J-11Bs is more equivalent of the Russian Su-27SM2 variant
The upgraded Su-27SM2 has improved radar and engines, however if the new Al-31 is fitted this jet will supercruise, so the J-11B still can not be compared to the modern Su-35 and upgraded Su-30SM since it lacks TVC nozzles, in fact the Su-27SM3 is just a downgraded Su-35BM with lower thrust engines.
The Su-30SM is the Russian equivalent of the Su-30MKI with upgraded avionics
Контракт на поставку 30 многоцелевых истребителей Су-30СМ подписан Минобороны России с производителем этих боевых машин, корпорацией "Иркут". Военно-воздушные силы страны должны получить их к 2015 году.
Многоцелевой истребитель Су-30СМ, разработанный "ОКБ Сухого", продолжает линейку боевых самолетов семейства Су-30МКИ. Эти истребители, серийно выпускаемые Иркутским авиационным заводом – филиалом ОАО "Корпорация "Иркут", успешно конкурируют на мировом рынке с современными боевыми самолетами иностранного производства, указал представитель Минобороны.
