China’s military sent 28 warplanes into airspace controlled by Taiwan on Tuesday — a record number since it began flying sorties off the coast of Taiwan on a near-daily basis last year. In response, Taiwan scrambled jet fighters, activated missile defense systems and issued warnings to the Chinese pilots. The tensions came a day after President Biden successfully pushed NATO leaders to declare China to be a security risk for the first time. China has repeatedly warned the U.S. against intervening in Taiwan, which China claims as its sovereign territory.
