Her office said she will also go to South Korea and Japan, but made no mention of a Taiwan visit.Taiwan's foreign ministry said it had no comment on reports of Pelosi's travel plans, but the White House - which would not confirm the trip - said she had the right to go.Beijing's responses could include firing missiles near Taiwan, large-scale air or naval activities, or further "spurious legal claims" such as China's assertion that the Taiwan Strait is not an international waterway, White House national security spokesperson John Kirby told reporters in Washington on Monday."We will not take the bait or engage in sabre rattling. At the same time, we will not be intimidated," Kirby said.'GROSS INTERFERENCE'Four sources said Pelosi was scheduled to meet a small group of activists who are outspoken about China's human rights record on Wednesday afternoon.The meeting is likely to take place at the National Human Rights Museum at New Taipei City, according to a source with direct knowledge of the matter.On Monday, Chinese foreign ministry spokesperson Zhao Lijian said it would be "a gross interference in China's internal affairs" if Pelosi visits Taiwan, and warned that "the Chinese People's Liberation Army will never sit idly by."Asked what kind of measures the PLA might take, Zhao said: "if she dares to go, then let us wait and see."China views visits by U.S. officials to Taiwan, a self-ruled island claimed by Beijing, as sending an encouraging signal to the pro-independence camp in the island. Washington does not have official diplomatic ties with Taiwan but is bound by U.S. law to provide the island with the means to defend itself.A visit by Pelosi, who is second in the line of succession to the U.S. presidency and a long-time critic of China, would come amid worsening ties between Washington and Beijing.The White House has dismissed China's rhetoric as groundless and inappropriate.'RIGHT TO VISIT'Kirby said that nothing about Pelosi's possible trip changed U.S. policy toward Taiwan, and that Beijing was well aware the division of powers within the U.S. government meant Pelosi would make her own decisions about the visit."The speaker has the right to visit Taiwan," he told the White House briefing.During a phone call last Thursday, Chinese President Xi Jinping warned U.S. President Joe Biden that Washington should abide by the one-China principle and "those who play with fire will perish by it".Biden told Xi that U.S. policy on Taiwan had not changed and that Washington strongly opposes unilateral efforts to change the status quo or undermine peace and stability across the Taiwan Strait.Beijing considers Taiwan to be part of its territory and has never renounced using force to bring the island under its control. Taiwan rejects China's sovereignty claims and says only its people can decide the island's future.Register now for FREE unlimited access to Reuters.comReporting by Yimou Lee and Sarah Wu;
