Taiwan on Monday again denied it had had any tariff talks with the United States that included discussion of exchange rate policy, after the Taiwan dollar surged against the U.S. dollar on speculation Washington had asked for it to appreciate.

Taiwan's trade office clarifies that recent tariff discussions with the United States did not involve currency exchange rates. The central bank of Taiwan was also not part of these discussions. This announcement follows speculation that the United States had pressured Taiwan to allow its currency to appreciate.

Investors are watching closely central bank actions after chatter that the authorities were tolerating a stronger currency to win concessions from the U.S.
