Actually it's not for China. That was China's promise to the world. No matter what happens as long as you don't block trade from me China will trade with you. They even do this with Taiwan, and believe me, China always keeps it's word.
There are countries accused of all sorts of things, yet China will never stop trading. Russia, Iran, North Korea, Belarus, Serbia, Egypt, I could go on. What does this say to BRICS nations if China picked a side. They're trapped by their own promise. But it's one that keeps them consistent regardless of how the world turns.
China's not angry, they're just clarifying. The agreement on the tariffs after April 2nd were reduced to 10% on both sides. Additionally, for the fentanyl tariffs, China has other countermeasures in place that will be removed if the fentanyl tariffs are removed. How are people reading this as if China is angry. Why would China be angry about something they agreed to?
