American brands like Nike and Guess are facing severe headwinds in China, with Nike reporting double-digit revenue declines and Guess closing all its Chinese stores. This slump reflects a broader trend where U.S. companies, once eager for China's growth, now struggle against fierce local competition. Starbucks sold its majority stake in China to Boyu Capital, highlighting the challenges. A decade ago, China was seen as a top growth market, but now geopolitical tensions, amplified by President Trump's May visit, are pushing Washington and Beijing toward a strained relationship, making American companies feel less invested in cooperation.
