What is China’s anti-sanctions law and how does it work?

The invocation of the anti-sanctions law signals a significant escalation in China's response to foreign economic pressures, particularly from the US. By actively blocking sanctions, China is not only defending its oil industry but also sending a message to other nations about its resolve to uphold its sovereignty. This development could lead to further strain in US-China relations, as both countries navigate a complex landscape of sanctions and counter-sanctions.
