Correct. For her immediate defense needs, China is self-sufficiant. She has no need to purchase weapons from others, China's systems get better with every generation.
What China needs is teck--and she's getting it, as already stated, from all over the world...including the U.S.
China is in no danger of military assault from ANY country for the forseeable future so the goal of the PLA is steady improvement in systems and capabilities. In that case, buying Asian weapons, even top quality S.K. and Japaonese systems is a waste of money.
One danger of the current spy/copy paradigm is that the Middle Kingdom will eventually find itself in the same technological cul-de-sac as the old Soviet Union: producers of competent, quality weapons and systems that are ALWAYS and FOREVER one to two generations behind the only country that matters: mine, America.
No other country threatens Chinese hegemony in east Asia/West Pacific. China must eventually build a large, modern, all-volunteer defence force based on indigenous, not copied tech. It will take another couple generations. At that point, other Asian countries will be trying to copy Chinese weapons and tactics.

(BTW, I am a loyal and patriotic American--my favorite country. But it is time for China, the world's oldest and largest state, to become the economic and military power that she was for two thousand years. China will not be a threat to world peace, as the Soviet Union was--she will be a defender of world stability, either in competition with, or partnership with America...but America's equal and superior to all other nations in power and influance.)
