A Pentagon report on China's military power says Beijing is exceeding previous projections of how quickly it is building up its nuclear weapons arsenal and is "almost certainly" learning lessons from Russia's war in Ukraine about what a conflict over Taiwan might look like.
The report released on Thursday also warns that China may be pursuing a new intercontinental missile system using conventional arms that, if fielded, would allow Beijing "to threaten conventional strikes against targets in the continental United States, Hawaii and Alaska".
The China report comes a month before an expected meeting between Chinese leader Xi Jinping and President Joe Biden on the sidelines of next month's Asia-Pacific Economic Cooperation summit in San Francisco.
