TOKYO, July 11 (Reuters) - U.S. threats of tariffs on an additional $200 billion worth of Chinese goods sent Asian stocks lower on Wednesday, with China's markets leading the declines, as trade tensions between the world's two biggest economies worsened.
Washington proposed the extra tariffs after efforts to negotiate a solution to the dispute failed to reach an agreement, senior administration officials said on Tuesday. United States had just imposed tariffs on $34 billion worth of Chinese goods on Friday, drawing immediate retaliatory duties from Beijing on U.S. imports in the first shots of a heated trade war. U.S. President Donald Trump had warned then that his country may ultimately impose tariffs on more than $500 billion worth of Chinese imports.

"The markets still remain sensitive to the trade-related theme, which is something investors have to take into account for the long term," said Yoshinori Shigemi, global market strategist at JPMorgan (NYSE:JPM) Asset Management in Tokyo.
"At the same time, the trade dispute can easily be blamed for a variety of ills. But it could mask over factors that could also weigh on equities in the longer run, such as tighter monetary policies led by the United States."
