We've seen the results of this just this year when its turned out China has enough oil reserves to buffer the reduced output from the Iran war. China had been bringing in Iran/Venezuela/Russia oil for years despite U.S./EU sanctions. That's not spy craft. That's China looking after itself and not bowing to western hegimony.

Nobody apart form US has issue with current China - if folks in US are getting the idea from US media that whole world is on some jihad against China thats laughable - nope its just US, yet another failed effort that will backfire way worse than doing nothing, ie like Iran. We don't want part in that. China is not expansionist unlike russia, it doesn't have that desperate need to promote their regime and way of doing things on whole world and murder anybody rejecting it. This fearmongering is simply not working outside US borders.

Now in the past there were many gentlemen agreements between nations plus the risk of aircraft carrier group coming your way or getting kicked out of SWIFT network, but that has been overused recently so nobody cares that much.
