Michael O'Hanlon, a senior fellow at the Brookings Institution, pointed out that the United States has a deep dependence on China in the short term, especially in the supply chain security of critical sectors such as pharmaceuticals, which cannot be ignored. He sharply noted that the main ingredients of many life-saving drugs in the U.S. are sourced from China, stating, "We cannot fantasize that we can still gain an advantage after cutting off ties with China." O'Hanlon further emphasized that the U.S. lacks the capital to implement extreme brinkmanship in handling China-U.S. relations, and there is an objective interdependent relationship between the two sides.
