Experts See a Message in Chinese Balloons Flying Over Taiwan

The balloon flights may, nonetheless, be part of the “gray zone” tactics that China uses to warn Taiwan of its military strength and options, without tipping into baldfaced confrontation. The timing of the balloon flights, close to Taiwan’s election, was telling, said Ko Yong-Sen, a research fellow at the Institute for National Defense and Security Research, a think tank in Taipei funded by Taiwan’s defense ministry. Mr. Ko has analyzed the pattern of recent sightings. “It’s more an intimidating effect in what happens to be a quite sensitive time, with…

China Has Paused Its Spy Balloon Operations, U.S. Officials Say

American officials said on Friday that China had paused its spy balloon operations after one of the craft floated across much of the United States early this year and was shot down off the coast of South Carolina, setting off a diplomatic crisis between the rival powers. The officials said that they did not know how long the pause would last, but that given the investments the Chinese government had made in the balloon program, Beijing was likely to restart it. The spy balloon that crossed the United States was…

Biden Says Xi Was Not Informed About Spy Balloon

This was not the first time Mr. Biden has made off-the-cuff remarks about foreign policy during an evening fund-raiser. At another such event in New York in October, he warned donors that the world was closer to nuclear destruction than at any time since John F. Kennedy faced off against Nikita S. Khrushchev over Soviet missiles in Cuba in 1962. “We have not faced the prospect of Armageddon since Kennedy and the Cuban Missile Crisis,” Mr. Biden said then, prompting a nervous reaction. In California on Tuesday, Mr. Biden was…

Tracking the Chinese Balloon From Space

Methodology — Finding the Chinese Balloon in Satellite Images A satellite collects images of the Earth by taking pictures in different wavelengths of light and stitching them together. The satellite photographs the same location on the ground from slightly different vantage points as it moves at high speeds overhead. An object like the Chinese balloon, floating somewhere between the satellite and the ground, looks like it is hovering over different parts of the Earth in each image. This phenomenon, where an object looks like it is in different places depending…

Plans in Congress on China and TikTok Face Hurdles After Spy Balloon Furor

WASHINGTON — Republicans and Democrats are pressing for major legislation to counter rising threats from China, but mere weeks into the new Congress, a bipartisan consensus is at risk of dissipating amid disputes about what steps to take and a desire among many Republicans to wield the issue as a weapon against President Biden. In the House and Senate, leading lawmakers in both parties have managed in an otherwise bitterly divided Congress to stay unified about the need to confront the dangers posed by China’s militarization, its deepening ties with…

Inside the Hunt for U.F.O.s at the End of the World

DEADHORSE, Alaska — Really? That’s it? The United States military is capable of many things, but finding the remnants of an unidentified flying object scattered across a blinding expanse of Arctic ice in minus-30-degree weather using six available hours of daylight is not one of them. The search for a downed U.F.O. began and ended near this oil-camp town at the frozen edge of the world, where Navy pilots flying P-8 Poseidons finally gave up on Friday, ending their mission with no answers. Hours later and some 500 miles away,…

China Says U.S. Is ‘Not Qualified’ to Issue Orders on Arms

Bristling against U.S. claims that Beijing may be poised to send “lethal support” to help Russia’s war in Ukraine, China accused the Biden administration on Monday of spreading lies and defended China’s close partnership with Russia. The remarks, by a spokesman from the Chinese Ministry of Foreign Affairs, were part of a series of diplomatic moves as China’s leader, Xi Jinping, tries to preserve ties with President Vladimir V. Putin of Russia while casting Beijing as a blameless onlooker in Russia’s invasion of Ukraine, trying only to coax Moscow and…

China’s Balloons Draw Attention to an Overlooked Canada-U.S. Partnership

The interest in balloons, other than the party and clown varieties, has recently reached levels perhaps not seen in Canada since the 19th century. It all began, of course, with a giant Chinese surveillance balloon that floated above British Columbia before drifting around the United States and ultimately being blown up by the United States Air Force over the Atlantic. Since then, three other objects have met a similar fate including one brought down over Yukon and another shot down above Lake Huron. [Read: A Rising Awareness That Balloons Are…

Navy Divers Complete Recovery of Chinese Spy Balloon Debris

WASHINGTON — Navy divers on Thursday completed an operation to recover pieces of the Chinese spy balloon that a U.S. fighter jet had shot down off the coast of South Carolina this month, according to U.S. Northern Command. The recovered debris was sent to the Federal Bureau of Investigation’s laboratory in Quantico, Va., for further analysis, including “counterintelligence exploitation,” raising the possibility of greater visibility into what the balloon had been able to capture as it traversed parts of the United States. In remarks on Thursday, President Biden called the…

U.S. and China Vie in Hazy Zone Where Balloons, U.F.O.s and Missiles Fly

WASHINGTON — During the Cold War, American strategists feared the Soviet Union was outpacing the United States in arms production, potentially leading to a so-called missile gap. Now, U.S. officials are worried about a literal gap called near space and China’s growing presence there. High above earth, but below orbiting satellites, the United States and China are testing new defense systems. China’s exploitation of the zone with aerial craft and advanced munitions suggests it is pulling ahead of its superpower rival in important ways. This little-known and little-seen strategic contest…
