Lack of US-China trade deal weighs on Asian markets

Markets in Asia were down on Monday as the lack of a US-China trade deal cast a cloud over nervous traders. Investors watched the latest developments warily in the trade war between the world's top two economies, after negotiations in Washington ended Friday without agreement and a tariff hike on Chinese imports went into effect. Almost all Asian markets were lower as the week's trading began, with Tokyo's benchmark Nikkei 225 index closing down 0.7 percent.
