Lawmakers called out China’s growing footprint at the

United Nations

, the US ambassador to the UN, said that China’s peacekeeping forces are generally well-equipped and better prepared for UN missions than those of other member states.

“That said, I don’t think for a second that they don’t serve a dual purpose as eyes and ears on the ground for the Chinese Communist Party,” added Waltz.
