Biden claimed that Pelosi was a separate branch of government and that he did not have control over her travel plans completely false. The supreme court decided in Haig vs Agee that the US State Department could definitely prevent travel of any US citizen if it was a threat to national security or foreign policy. 拜登聲稱佩洛西是政府的一個獨立部門，他無法控制她的旅行計劃，這完全是錯誤的。 最高法院在黑格訴阿吉案中裁定，如果任何美國公民的旅行對國家安全或外交政策構成威脅，美國國務院絕對可以阻止其旅行

“In a 7-to-2 decision, the Court held that Passport Act of 1926 and other congressional statutes implicitly granted the Secretary of State the power to revoke passports. The Court noted Congress’s historical recognition of “Executive authority to withhold passports on the basis of substantial reasons of national security and foreign policy.” The Court further held that because the regulations were limited to cases in which there was a likelihood of “serious damage” to foreign policy, Agee’s claims concerning the First Amendment, the Fifth Amendment, and the right to travel were “without merit.”

If Biden does not seek to invoke Haig vs Agee–as any reasonable leader would–we can infer that the Biden WH does not see Pelosi’s trip as causing damage to foreign policy, i.e. Pelosi may be carrying out foreign policy.

WASHINGTON, July 28 (Reuters) – U.S. President Joe Biden and China’s Xi Jinping held a fifth call as leaders on Thursday, speaking for more than two hours, as concerns mounted over a possible visit to Chinese-claimed Taiwan by U.S. House of Representatives Speaker Nancy Pelosi.

The White House said the call began at 8:33 a.m. (1233 GMT) and ended at 10:50 a.m. (1450 GMT). U.S. officials had said it would have a broad agenda, including discussion of Russia’s invasion of Ukraine, which China has yet to condemn.

At its core, U.S. officials see the exchange as another chance to manage competition between the world’s two largest economies, whose ties have been increasingly clouded by tensions over democratically governed Taiwan, which Xi has vowed to reunite with the mainland, by force if necessary.

Beijing has issued escalating warnings about repercussions should Pelosi visit Taiwan, a move that would be a dramatic, though not unprecedented, show of U.S. support for the island, which says it is facing increasing Chinese military and economic threats.

Washington does not have official relations with Taiwan and follows a “one-China” policy that recognizes Beijing, not Taipei, diplomatically. But it is obliged by U.S. law to provide the island with the means to defend itself, and pressure has been mounting in Congress for more explicit support.

“This is about keeping the lines of communication open with the president of China, one of the most consequential bilateral relationships that we have, not just in that region, but around the world, because it touches so much,” White House national security spokesman John Kirby told reporters on Wednesday.

One person briefed on planning for the call said the Biden administration thinks leader-to-leader engagement is the best way to lower tensions over Taiwan.

Some analysts believe Xi also has an interest in avoiding escalation as he seeks an unprecedented third term in office at a congress of China’s ruling Communist Party expected in the fall.

Biden also wanted to discuss climate and economic competition issues, the person briefed said, as well as the idea of placing a price cap on Russian oil to punish Moscow for its war in Ukraine, an issue Treasury Secretary Janet Yellen raised with Chinese counterparts earlier in July. read more

The Biden administration has been debating whether to lift some tariffs on Chinese goods as a way to ease soaring inflation, but U.S. officials have said a decision was not expected ahead of the call. read more

When Biden last spoke to Xi in March, he warned of “consequences” if Beijing gave material support for Russia’s war, and the U.S. government believes that that red line has not been crossed in the months since.

Taiwan has complained of stepped-up Chinese military manoeuvres over the past two years to try and force it to accept Beijing’s sovereignty. Just ahead of Thursday’s call, Taiwan’s military said it fired flares to warn away a drone that “glanced by” a strategically located and heavily fortified island close to the Chinese coast that was possibly probing its defences. read more

TOXIC TIES
The White House has reiterated that its “one-China” policy has not changed despite speculation over a possible trip by Pelosi, which the speaker has yet to confirm.

The last time a speaker of the U.S. House visited Taiwan was in 1997, and as a co-equal branch of government, the U.S. executive has little control over congressional travel.

China has grown more powerful militarily and economically since, and some analysts worry such a visit at a time of fraught ties, could spur a crisis across the 100-mile (160-km) wide Taiwan Strait waterway separating China and Taiwan.

“The relationship is in such a toxic state. Mutual distrust is really at an all-time high. I think people don’t realize how dangerous this particular moment is,” said Bonnie Glaser, a China expert at the German Marshall Fund of the United States.

She said Biden and Xi needed to focus their call on de-escalation, including possible mechanisms to reduce the risk of mishaps.

Kirby said the administration has been in touch with Pelosi’s office to make sure she has “all the context” she needs to make decisions about her travel.

China has given few clues to specific responses it might take if Pelosi, a long time critic of China, particularly on human rights issues, does go to Taiwan.

Martin Chorzempa, a senior research fellow at the Peterson Institute for International Economics, said playing up the Taiwan issue could serve Xi as a domestic distraction from China’s slowing economy, but “any reaction strong enough to trigger U.S. sanctions would create massive damage to China and the world economy.” read more

China’s state media said on Thursday the country will try hard to achieve the best possible results for the economy this year, dropping previous calls that it will strive to meet its 2022 growth target. This followed a high-level Communist Party meeting chaired by Xi. read more

Scott Kennedy of Washington’s Center for Strategic and International Studies think tank, said he did not believe the two sides were on the edge of a crisis, but “the risk of a major crisis is well above zero” and a Biden-Xi call was important to avoid an unwanted clash.

“Beijing, Taipei and Washington are full of people steeped in how to send and interpret signals conveying threats and reassurance, and I’m sure no one wants a war right now.”
