Nothing,anything about NK is OK.
In my veiw..China havn't export any morden tanks after 1990.(What exported maybe old Type-59/69? No Type 80+ or better one)
About China in Korean War II?
IMO..
If SK/US strike NK's nuclear base,with out any ground attack. China will do noting as usual
If NK attack SK,invasion with ground forces,US/SK Counter-attack to 38 Line . China will noting as usual, maybe some weapon export to NK
If SK/US invasion NK or want to destory NK goverment. China should send some ground forces to take control NK.Withoout breaking war with US/SK.
Any way,any action make war between two Nuke country is idiot action.
What you,we need? Peace only. :yes:
