I am very confident that China's 6th generation fighter equivalent will be ready for service by mid 2030s.
They were already researching it before J-20 came into service in 2017 and there has been some information already leaked about its variable cycle engine. This is something it will share with the UK's Tempest fighter that is due for service in 2035 and I think the US 6th gen fighter will also use them.
The military tech gap between US and China is slowly closing and not increasing as some imagine.
Stick with Chinese for now acquire tots, become involved the Turkish fighter program.
