This is to be expected. We already know that China switched from Venezuelan to Canadian crude since last November after the Trump-Xi meeting:

So the US already gave China ample time to reroute its oil supply before the recent operation in Venezuela. It’s not hard to see that the US is picking off the anti-American countries one by one, from Venezuela to Iran, to gain control in Latin America and the Middle East.

Meanwhile, China’s rapprochement with South Korea recently is also to be expected as the US withdraws from the Asia-Pacific region and letting Japan to take the brunt.

If you think the US’s goal is to defeat China, then you’re thinking too small. The US wants to eat the entire globe.
