China warned world leaders to not interfere with the country's plan to reunify with Taiwan, adding that doing so would lead to severe consequences.

“Any scheme to interfere in China’s internal affairs is bound to meet the strong opposition of all Chinese and any move to obstruct China’s reunification is bound to be crushed by the wheels of history,” the Chinese foreign minister said on Saturday at the U.N. General Assembly.

House Speaker Nancy Pelosi (D-Calif.) and other American lawmakers make a trip to Taipei this summer as part of a tour around the Indo-Pacific region to which China strongly reacts.

“It gravely undermines peace and stability across the Taiwan Strait, and sends a seriously wrong signal to the separatist forces for ‘Taiwan independence,’” said the Chinese Ministry of Foreign Affairs of Pelosi’s trip.

Only when China is fully reunified can there be true peace across the Taiwan Strait,” Wang Yi, China’s foreign minister, said at the U.N. General Assembly on Saturday.
