Well, every nation strives for power, hence influencing international bodies to make decisions in ones interest is not exactly a China-only feature, neither is the confluence of economic interest of individual companies and political interest of each respective nation, or the extraterritorial application of national law.

All this is regular US-practise and it has gone way over the top, in my opinion.

Certainly economic power will also strive for political power and influence along its economic strength, something China has held back until the explosive release from 2012-13.

In order to protect assets and other economic interests which are subject to the law of the respective land, having some domestic lobby is necessary. I wouldn't know a single western nation that wouldn't go down the same road in a similar situation (but not using such crude means).

On the receiving end, you can't sell domestic assets to a foreign nation and seriously expect no meddling in your internal affairs, whether it is an Australian iron ore mine or a US rare earth mine being sold to China owners (yes, Trump actually did exactly that).

How much of this lobby-strive is communist and how much of it is the Chinese nation is irrelevant, as both share the same interest in terms of the nation exerting power.
