Stock market today: Asia shares trade mostly lower as as investors weigh impact of US-China tariffs

Asian shares are trading mostly lower as markets mull the impact of tariffs being imposed by the United States and China. Benchmarks fell in early Wednesday trading in Tokyo, Hong Kong and Shanghai, while rising in Sydney and Seoul. Calm returned to Wall Street, and tech stocks led U.S. indexes higher. The S&P 500 rose 0.7% Tuesday, a day after swinging sharply on worries that President Donald Trump’s tariffs could spark a trade war that would hurt economies around the world. The Dow Jones Industrial Average rose 0.3%, and the Nasdaq composite climbed 1.4%. Oil prices fell. Trump has delayed planned tariffs on goods from Canada and Mexico while imposing them on Chinese imports. China's tariffs on some U.S. imports start next week.
