SHANGHAI, Aug 1 (Reuters) - Asian shares were higher on Wednesday, tracking the firmer Wall Street finish though reports that Washington plans to raise tariffs on $200 billion of Chinese goods have put the focus back on volatile Sino-U.S. trade relations.

Global markets inched higher on Tuesday, helped by a Bloomberg report that the U.S. and China were seeking to resume trade talks to defuse the battle over import tariffs.

However, later reports that the U.S. plans tariffs of 25 percent on $200 billion in Chinese imports have injected some uncertainty back into financial markets, with the offshore yuan and the Australian dollar lower.

A source told Reuters that an announcement on Washington's tariff plans for China could come as early as Wednesday.

The Dow Jones Industrial Average rose 0.43 percent to 25,415.19, the S&P 500 gained 0.49 percent to 2,816.29 and the Nasdaq Composite added 0.55 percent to 7,671.79.

Tech shares across the region may get a boost after Apple Inc. beat Wall Street expectations for its quarterly results thanks to robust sales of its top-of-the-line iPhone X. . The company's shares rose 3.4 percent to $196.80 in after-hours trade.

Investors will also be watching data from around the region, including manufacturing activity numbers from China, for indications of the outlook for the global economy.

Data from Australia showed a slowdown in manufacturing activity in July, with the Commonwealth Bank/Markit purchasing managers index at its lowest level in nearly two years.

Australian shares ticked down 0.1 percent after earlier moving higher on Wednesday.
