NEW YORK, Aug. 5 (Xinhua) -- The U.S. dollar declined on Monday, as trade concerns persisted around global foreign exchange market, driving up safe-haven currencies including the Japanese yen and the Swiss franc.

The dollar index, which measures the greenback against six major peers, fell 0.57 percent at 97.5234 in late trading.

In late New York trading, the euro rose to 1.1202 dollars from 1.1111 dollars in the previous session, and the British pound fell to 1.2141 dollars from 1.2157 U.S. dollars in the previous session. The Australian dollar was down to 0.6760 dollar from 0.6795 dollar.

The U.S. dollar bought 106.03 Japanese yen, lower than 106.56 Japanese yen of the previous session. The U.S. dollar fell to 0.9736 Swiss franc from 0.9824 Swiss franc, and it was up to 1.3217 Canadian dollars from 1.3211 Canadian dollars.

U.S. President Donald Trump tweeted on Thursday that he would place an additional 10-percent tariff on the remaining 300 billion U.S. dollars worth of Chinese imports starting on Sept. 1.

The announcement has disrupted market expectations, causing global stock and foreign exchange markets to slump, said Zhang Yansheng, a researcher with the China Center for International Economic Exchanges.

Chinese yuan weakened beyond 7 yuan per U.S. dollar on Monday. The People's Bank of China (PBOC) attributed the weakening of the currency to factors including unilateral and protectionist measures, as well as the expectation of additional tariffs on Chinese goods.

The central bank reiterated in a statement on Monday that it is confident in its capability of keeping the yuan's exchange rate basically stable. Enditem
