<h1>Asian markets fall as Japanese GDP contraction, China-Japan diplomatic tensions and Fed rate uncertainty weigh on investors</h1> Asian markets fell broadly after a weak U.S. finish, with Japan's benchmark down following a reported quarterly GDP contraction and the dollar rising versus the yen. Markets also reacted to deteriorating diplomatic ties between China and Japan after remarks by a Japanese leader about Taiwan, prompting Chinese travel and study warnings and forcing reassessments of regional risk. Equity gains in South Korea were driven by tech stock cooperation on AI, while U.S. futures drifted higher ahead of a major chipmaker's earnings report that may affect valuations. Uncertainty about further Federal Reserve rate cuts and volatile commodity and crypto moves added downside risk for investors.
