I'm sure they have other procurement projects going on, but in my uninformed opinion I'd think they should probably concentrate on anti-ship and anti-aircraft weapons. They've probably already lost if they need to use tanks and anti-tank weapons.
So I’m not sure how real is China threat for East Asia.
If you look into their history, stable China always translated to stable East Asia.
I’m really worried about all these trends and military moves on that region. We might make East Asia the next Middle East. Not to mention once it happened to them during the colonization and it took them ages to recover.
