Lawmakers Press Biden Administration for Tougher Curbs on China Tech

Republican lawmakers are faulting the Biden administration’s enforcement of restrictions on China’s access to American technology, saying that the administration is still allowing semiconductors and other American innovation to flow to Beijing that could ultimately aid China in a military conflict. In a report released on Thursday, the House Foreign Affairs Committee said the administration had failed to enforce export controls that limit sales of advanced technology to China. The federal government has been steadily ramping up limits on sales to China of advanced chips and chip-making equipment over the…

Can U.S.-China Student Exchanges Survive Geopolitics?

On a cool Saturday morning, in a hotel basement in Beijing, throngs of young Chinese gathered to do what millions had done before them: dream of an American education. At a college fair organized by the United States Embassy, the students and their parents hovered over rows of booths advertising American universities. As a mascot of a bald eagle worked the crowd, they posed eagerly for photos. But beneath the festive atmosphere thrummed a note of anxiety. Did America still want Chinese students? And were Chinese students sure they wanted…

What Are the Risks of A.I. Drones and Weapons?

Swarms of killer drones are likely to soon be a standard feature of battlefields around the world. That has ignited debate over how or whether to regulate their use and spurred concerns about the prospect of eventually turning life-or-death decisions over to artificial intelligence programs. Here is an overview of how the technology has evolved, what types of weapons are being developed and how the debate is unfolding. How new are these weapons? Eventually, artificial intelligence should allow weapons systems to make their own decisions about selecting certain kinds of…

A.I. Killer Drones Are Becoming Reality. Nations Disagree on Limits.

It seems like something out of science fiction: swarms of killer robots that hunt down targets on their own and are capable of flying in for the kill without any human signing off. But it is approaching reality as the United States, China and a handful of other nations make rapid progress in developing and deploying new technology that has the potential to reshape the nature of warfare by turning life and death decisions over to autonomous drones equipped with artificial intelligence programs. That prospect is so worrying to many…

Chinese Jet Flies Within 10 Feet of B-52, U.S. Says

A Chinese fighter jet came within 10 feet of a U.S. Air Force B-52 bomber over the South China Sea this week in a nighttime maneuver that nearly caused a collision, the United States military said on Thursday. The pilot of the J-11 jet that drew close to the B-52 in international airspace on Tuesday night “flew in an unsafe and unprofessional manner” and with “uncontrolled excessive speed,” the U.S. Indo-Pacific Command said in a statement. The U.S. military also released a grainy, black-and-white video that it said showed the…

China’s Military is Making Risky Moves and Adding Nuclear Warheads, U.S. Says

Risky Maneuvers Since the fall of 2021, the Pentagon report says, the United States has recorded more than 180 intercepts of U.S. aircraft by Chinese military forces in the region. Beijing has long bristled at the U.S. military aircraft and ships that operate in international skies and seas near China. China has been increasingly assertive in the region, from building military infrastructure in the disputed South China Sea to buzzing planes flown by the United States, Canada and other Western allies. Such moves risk a midair crash and a wider…

Israel-Hamas War Adds to Surge in Global Weapons Sales

Just days after the assault by Hamas ignited a new war in the Middle East, shipments of American weapons began arriving in Israel: smart bombs, ammunition and interceptors for the Iron Dome missile-defense system. When President Biden meets in Israel on Wednesday with Prime Minister Benjamin Netanyahu, more military aid is a likely topic. The conflict between Israel and Hamas is just the latest impetus behind a boom in international arms sales that is bolstering profits and weapons-making capacity among American suppliers. The surge in sales is providing the Biden…

In Risky Hunt for Secrets, U.S. and China Expand Global Spy Operations

As China’s spy balloon drifted across the continental United States in February, American intelligence agencies learned that President Xi Jinping of China had become enraged with senior Chinese military generals. The spy agencies had been trying to understand what Mr. Xi knew and what actions he would take as the balloon, originally aimed at U.S. military bases in Guam and Hawaii, was blown off course. Mr. Xi was not opposed to risky spying operations against the United States, but American intelligence agencies concluded that the People’s Liberation Army had kept…

Pentagon Vows to Move Quickly to Buy More Drones, Citing China Threat

The Pentagon announced on Monday that it would buy thousands of unmanned drones and other autonomous devices over the next two years, adding that it had been far too slow to embrace new technology that is “small, smart, cheap” and that could bolster the U.S. military as it prepares for possible future conflict with China. The commitment came from Kathleen Hicks, the deputy defense secretary. She said in a speech at a gathering of military contractors that the Pentagon would soon change how it buys the kind of autonomous devices…
