China has put new focus on airships hovering in a part of the sky just before outer space. Although Beijing says they're scientific, analysts say the data helps the country develop advanced weapons.
Lawmakers at Tuesday's hearing on U.S.-China competition discussed a range of threats, including China's foreign farmland holdings. A South Dakota congressman argues even a small amount is concerning.
The two leaders met in Beijing and discussed the war in Ukraine, a week after China released a position paper, calling for a cease-fire and peace talks between Russia and Ukraine.
As Russia's war in Ukraine enters its second year, Beijing has repeatedly said it would broker any cease-fire talks, a proposal Ukrainians are wary of because of China's close ties with Moscow.
The meeting is the highest level of contact between the two nations since the discovery of a Chinese balloon in U.S. airspace at the beginning of this month.
