Washington, Aug 1 (IANS): US House Speaker Nancy Pelosi is expected to visit Taiwan as part of her tour of Asia, according to a senior Taiwanese government official and a US official, despite warnings from Joe Biden administration officials, who are worried about China's response to such a high-profile visit, the media reported.

The stop -- the first for a US House speaker in 25 years -- is not currently on Pelosi's public itinerary and comes at a time when US-China relations are already at a low point, CNN reported.

The Taiwanese official added that she is expected to stay in Taiwan overnight. It is unclear when exactly Pelosi will land in Taipei.

The US official added that Defense Department officials are working around the clock on monitoring any Chinese movements in the region and securing a plan to keep her safe.

During a regular foreign ministry briefing Monday, China warned against the "egregious political impact" of Pelosi's planned visit to the self-governing island that China claims as a part of its territory and reiterated that its military "won't sit by idly" if Beijing feels its "sovereignty and territorial integrity" is being threatened.

"We would like to tell the US once again that China is standing by, and the Chinese People's Liberation Army will never sit idly by. China will take resolute responses and strong countermeasures to defend its sovereignty and territorial integrity," Foreign Ministry spokesman Zhao Lijian told reporters, when asked about the fallout from Pelosi leading a congressional delegation to Taipei, CNN reported.
