Japan's government intends to continue pursuing diplomatic efforts to ensure peace and stability in the Taiwan Strait following the inauguration of Taiwan's new President Lai Ching-te.

In his inauguration speech on Monday, Lai refuted Beijing's claim that Taiwan is part of China, saying, "The Republic of China and the People's Republic of China are not subordinate to each other."

A Chinese government official criticized Lai's speech, saying the new president sent a dangerous signal that ignores public opinion, goes against the times, and undermines the peace and stability of the Taiwan Strait. The official said the speech exposed Lai's nature of being "a worker for Taiwan independence."

Japanese foreign ministry officials say they are concerned that tensions could escalate if Lai ratchets up his rhetoric, as the new president hasn't recognized the "One China" principle espoused by Beijing.

Chief Cabinet Secretary Hayashi Yoshimasa said ensuring the peace and stability of the Taiwan Strait is important for the international community, including Japan. Hayashi said Japan's consistent stance is that the country expects issues related to Taiwan to be peacefully resolved through dialogue.

Japanese officials say they will explain the country's stance to their Chinese counterparts on every possible occasion. They also say the government will continue diplomatic efforts to ensure the peace and stability of the Taiwan Strait, in cooperation with the United States and other allies.
