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.
The Taiwanese official added that she is expected to stay in Taiwan overnight. It is unclear when exactly Pelosi will land in Taipei.
“The question of Taiwan is the most sensitive, important core issue in China-US relations,” said Chinese Ambassador to the US Qin Gang at the Aspen Security Forum in July.
Biden said last month that the US military opposed Pelosi visiting Taiwan, though since then has refused to elaborate on the warnings. The White House has said it is up to the House speaker where she travels, and that they have little say in her decision.
Still, administration officials have worked over the past weeks to spell out the risks of a visit to Taiwan in meetings with Pelosi and her team. Defense Secretary Lloyd Austin recently said he’d discussed a visit to Asia with Pelosi.
The administration takes extra care for Pelosi’s security when she travels overseas because she is in the presidential line of succession.
Administration officials are concerned Pelosi’s trip comes at a particularly tense moment, as Xi is expected to seek an unprecedented third term at the upcoming Chinese Communist Party congress. Chinese party officials are expected to begin laying the groundwork for that conference in the coming weeks, putting pressure on the leadership in Beijing to show strength.
Officials also believe the Chinese leadership doesn’t completely grasp the political dynamics in the United States, leading to a misunderstanding over the significance of Pelosi’s potential visit. The officials say China may be confusing Pelosi’s visit with an official administration visit, since she and Biden are both Democrats. Administration officials are concerned that China doesn’t separate Pelosi from Biden much, if at all.
Pelosi has long been a critic of the Chinese Communist Party. She has met with pro-democracy dissidents and the Dalai Lama — the exiled Tibetan spiritual leader who remains a thorn in the side of the Chinese government. In 1991, Pelosi unfurled a black-and-white banner in Beijing’s Tiananmen Square to commemorate victims of the 1989 massacre, which said, “To those who died for democracy.” In recent years, she voiced support for the pro-democracy protests in Hong Kong.
The Chinese embassy to the United States has objected to her expected trip, which was planned for April before Pelosi tested positive for Covid-19, urging members of Congress to tell the speaker not to make it.
“I would say there’s been a full-court press from the Chinese embassy to discourage a trip to Taiwan,” Washington Democratic Rep. Rick Larsen, the co-chair of Congress’ US-China working group, told CNN. “I just don’t think it’s their business to tell us what we ought to be doing. That was my message back.”
Liu Pengyu, spokesperson of the Chinese Embassy in the US, responded that his office is in “regular contact” with members of Congress, including Larsen.
“On the Taiwan question, we have made our stance loud and clear,” Pengyu said. “The Embassy is making all our efforts to prevent the peace and stability across the Taiwan Strait and the stability of China-US relations being damaged by the potential visit of House Speaker Nancy Pelosi to Taiwan.”
“We hope serious consequences could be avoided,” he added. “This is in the common interests of both China and the US.”
Many Democrats and Republicans in Congress said it was Pelosi’s right to travel to Taiwan.
“It is Speaker Pelosi’s decision alone on whether or not to travel to Taiwan, not any other country,” said Illinois Republican Rep. Darin LaHood, Larsen’s Republican counterpart on the US-China working group. “In our democratic system — we operate with separate but equal branches of government.”
“It is inappropriate for foreign governments, including the Chinese government, to attempt to influence the ability or the right to travel for the speaker, members of Congress, or other US government officials to Taiwan or anywhere else around the world,” he added.
Other members appeared to be more cautious about the diplomatically sensitive trip.
California Democratic Rep. Judy Chu, the first Chinese American woman elected to Congress, said she has “always supported Taiwan.”
But when asked whether a Taiwan trip now would send the wrong message, Chu said, “You could look at it two ways. One is that the relationships are very strained right now. But on the other hand, you could say maybe that’s when Taiwan also needs to be shown the strength and the support.”
When asked what she thought, she said, “I leave it up to those who are going to make that decision.”
