China has intensified its economic pressure on Japan, with state-owned enterprises banning employees from travelling to its Asian neighbour, tour groups and a flagship forum being cancelled and Japanese film releases suspended.

Japan's Trade Minister Ryosei Akazawa said on Tuesday there are currently no particular changes in China's export control measures on rare earths and other materials. Akazawa's remarks come as Japan seeks to ease tensions with China amid an escalating dispute over Taiwan.

China advised its citizens Friday to refrain from traveling to Japan in the near future. It cited earlier attacks against Chinese in Japan and what it called Prime Minister Sanae Takaichi 's "erroneous remarks" on Taiwan, which it said undermined the atmosphere for China-Japan exchange.

The diplomatic row over comments on Taiwan has evolved from a war of words to Beijing advising its citizens against travelling and studying abroad in Japan.

China's Premier Li Qiang has no plans to meet with the Japanese prime minister on the sidelines of the upcoming G20 summit in South Africa, the Chinese foreign ministry said on Monday, as tensions over Taiwan deepen.
