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

Asian shares are trading mixed as markets mull the impact of tariffs being imposed by the United States and China. Benchmarks fell Wednesday in Hong Kong and Shanghai, while rising in Sydney and Seoul and being little changed in Tokyo. Calm returned to Wall Street, where 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. The Dow Jones Industrial Average rose 0.3%, the Nasdaq climbed 1.4%. 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.
