GYEONGJU, South Korea, Oct 30 (Reuters) - Taiwan's top

trade negotiator said on Thursday that she had met with a senior

U.S. trade official on the sidelines of the APEC summit in South

Korea, but could not provide any details of what they discussed.

Taiwan's exports to the United States are subject to a 20%

tariff, though Taiwan has been in negotiations to get that

reduced, which have yet to conclude. Semiconductors, a key

Taiwanese export, are currently excluded from the tariffs.

Jenni Yang told reporters in South Korea's Gyeongju, where

the Asia-Pacific Economic Cooperation (APEC) summit is taking

place, that she had had "exchanges" with Deputy United States

Trade Representative Rick Switzer.

However, she said that she could give no details and that

the content of the talks would be released in due course.

The United States Trade Representative Office did not

immediately respond to a request for comment sent outside of

Washington office hours.

Taiwan, which dominates the production of advanced

semiconductors powering the AI boom, has rejected a proposal

floated in U.S. media last month by U.S. Secretary of Commerce

Howard Lutnick for a 50-50 split in making chips.

But Taiwan has said it is considering forming a high-tech

strategic partnership with the U.S., which wants increased

Taiwanese investment.

Taiwan, home to the world's biggest contract chipmaker TSMC

, runs a large trade surplus with the United States.
