Why would americas foreign-policy advisors want to understand china's foreign-policy goals?

For starters, Trump abandoned the Trans-Pacific Partnership, a slap in the face to the 11 Asia-Pacific countries that had worked hard to reach an agreement that would have provided some modest economic benefits and kept them more closely linked to the U. S. economy. Then Trump launched his own trade war with China. But instead of lining up other key economic powers, he threatened or waged trade wars with most of them, too. Instead of presenting China with a united front, the United States has been facing China more or less alone, with substantially reduced leverage. The predictable result: a face-saving trade compromise that rolls back the clock and no progress on the real bones of contention with Beijing.

Explanation:

the far more important issue of China. To its credit, the Trump administration recognizes that China is the only possible peer competitor that the United States is likely to face for many decades. This realization is no great feat of genius, however. Reasonable people can disagree about the magnitude of the China challenge, but only a blind person could miss the worrisome implications of China's rise.

If you thought strategically, you'd start looking for ways to limit Chinese influence at the least cost and risk to the United States itself. You'd understand that the United States cannot halt or reverse Chinese economic growth (and certainly not without hurting itself), but you'd work hard to keep as many countries as possible on its side on the issues that matter, including advanced technology. In fact, you'd get serious about trying to prevent China from achieving a dominant position in potentially game-changing technologies like quantum computing and artificial intelligence. You'd be focused laserlike on maintaining a solid diplomatic position in Asia, and over time, you'd be looking for ways to drive a wedge between China and Russia, too. And you'd try hard not to get distracted by secondary issues and waste time, attention, political capital, or resources on them.
