Leaked documents reveal China's secret weapon agreement with Russia.

China secretly agreed to provide lethal aid to Russia in its war in Ukraine earlier this year, according to a US intercept of Russian intelligence revealed in leaked secret documents. The documents show that China approved the "provision of lethal aid" and planned to disguise military equipment as civilian items. The report provides the most detailed evidence to date of what led to a flurry of public and private Biden administration warnings to Beijing beginning in late February.
