North Korea criticized the United States over its arms sales and military support for Taiwan, accusing Washington of fueling tensions in the Taiwan Strait, state media KCNA said on Wednesday.

A KCNA commentary citing North Korean international affairs analyst Kim Myong Chol said U.S. policy on Taiwan was undermining peace and stability in the region and condemned the appearance of U.S.-sold fighter aircraft in Taiwan.

The U.S. “should think twice whether it is ready to stand in frontal confrontation with the powerful national power of the People’s Republic of China for the security of Taiwan and whether it can cope with its consequences,” it added.
