SINGAPORE (AP) — Asian shares were mostly higher on Tuesday as traders took the weaker yuan as a sign that Chinese exports can remain competitive even if a trade dispute with Washington heats up.

WALL STREET: A report the U.S. is preparing to impose tariffs on all imports from China weighed on sentiment. The S&P 500 index fell 0.7 percent to 2,641.25. The Dow Jones Industrial Average tumbled 1 percent to 24,442.92 and the Nasdaq composite gave up 1.6 percent to 7,050.29. The Russell 2000 index of smaller-company stocks dropped 0.4 percent to 1,447.31.

MORE CHINESE TARIFFS: On Monday, Bloomberg News reported that the Trump administration plans to announce a new wave of tariffs on Chinese goods in December, if upcoming talks between President Donald Trump and his Chinese counterpart Xi Jinping fail to substantially diffuse tensions. The report cited unnamed sources who said the tariffs could cover imports from China that have not already been hit by tariffs, amounting to up to $257 billion worth of imports. A weakening of the Chinese yuan, which can make exports more price competitive, lifted sentiment in Asia. The yuan had declined to 6.9644 per dollar by midday on Monday, the lowest level since May 2008. It fell to 6.9677 against the dollar on Tuesday.

ANALYST’S TAKE: The optimisim may be misplaced, said Jingyi Pan of IG. “Even a 10 percent depreciation of the yuan does not measure up to the expected impact from a lift in tariffs,” she said in a commentary. “This is not including the externalities ... from damage to business confidence and upon the regional supply chain.”
