Stock market today: Asian shares slip as worries grow about Trump's tariffs

Asia shares are mostly declining as worries grow about President Donald Trump imposing tariffs on key U.S. trading partners. Benchmarks fell in early Monday trading in Japan, Australia and South Korea. In China, shares declined in Hong Kong but were little changed in Shanghai. Analysts said Asian markets were bracing for volatility set off by a possible trade war escalation. Wall Street ended last week lower. Trump’s 25% tariffs on imports from Canada and Mexico and 10% tariffs on goods from China are to take effect Tuesday. Both Canada and Mexico have ordered retaliation.
