President Xi Jinping has a nickname in China. Instead of calling him directly by name, people commonly use Da Da, or Mr. Big.

After all, he is the nation’s most powerful politician in decades, serving a precedent-defying third term. He also dares to challenge the world’s biggest economy and China’s only real rival, promoting a multipolar global order instead of unchallenged U.S. dominance.

It should come as no surprise, then, that China is acting differently from Canada or Mexico as President Donald Trump imposes trade tariffs. Not willing to capitulate to what it sees as bullying, Beijing is taking the 10% extra levy in stride.
