President Donald Trump has suggested his outlook to the U.S.-China relationship with a six-word post on Truth Social. He mentioned the "G2," a term suggesting equal power between the U.S. and China, before a summit with Chinese leader Xi Jinping on Oct. 30 in Busan, South Korea. This term, first proposed in 2005, has come to imply a power balance that Beijing desires. Experts say this could delight China but worry U.S. allies, especially those in the Indo-Pacific region. Chinese commentators noted the term's use, suggesting a move toward a bipolar world. The concept was once explored but later discredited by Washington.
