China's control measures on dual-use items export to Japan are fully legitimate, justified and lawful, foreign ministry spokesperson Mao Ning said on Wednesday.

Mao said at a regular press briefing that Japanese Prime Minister Sanae Takaichi's erroneous remarks on Taiwan violated China's sovereignty and territorial integrity, blatantly interfered in China's internal affairs and threatened the use of force against China.

With the aim of defending national security and interests and fulfilling non-proliferation and other international obligations, China took measures in accordance with laws and regulations, Mao said, adding that these measures are fully legitimate, justified and lawful.

"We urge Japan to face up to the root cause of the issue, do soul-searching, rectify its wrongdoings and retract the erroneous remarks by Takaichi," the spokesperson said.
