The initial version labels Taiwan as part of China.

The updated version removes Taiwan from China.

The US Defense Department played a little trick by removing Taiwan, initially labeled as part of China in its Nuclear Posture Review, from the map of China.

A Pentagon spokesperson told The Japan Times Saturday that there was an “error” printed in the 2018 NPR, a legislatively-mandated review that establishes US nuclear policy, strategy, capabilities, and force posture for the next five to 10 years. The initial version was replaced on the Department of Defense’s website a few hours later with Taiwan removed from China.

The DoD added that its position on and policy toward Taiwan have not changed.

China firmly opposes the US report that presumptuously speculated about the intentions behind China’s development and played up the threat of China’s nuclear strength, spokesman Ren Guoqiang from China’s National Defense Ministry said Sunday.

China’s Foreign Ministry also commented Monday at a regular press conference that the report comes in line with the US National Security report and National Defense Report released not long ago, and called on the US to abandon its Cold War mentality and outdated concept of zero-sum games, and maintain international peace and stability with concrete actions.

Regarding Taiwan, China urged the US to abide by the One China Policy and the principles set forth in the Three Joint Communiqués, and stop “sending the wrong signal” to Taiwan independence forces and cease any official association or contact with Taiwan.

This is not the first time the US has challenged China on Taiwan since Donald Trump assumed the US presidency. Early in December 2016, Trump broke diplomatic tradition and made a 10-minute phone call with Taiwan leader Tsai Ing-wen.
