New Delhi, April 17 -- The Chinese Embassy in Japan said Thursday it has received multiple threats and accused Japanese authorities of failing to take effective measures despite its repeated reporting to police, as tensions between the two sides rise.

Shi Yong, acting Chinese ambassador to Japan, said the embassy on March 5 received a letter from a group claiming to comprise former police and military members and threatening attacks on China's diplomatic missions in Japan and "wiping out all Chinese" in the country.

The embassy said on X that it immediately reported to Japanese police and criticized they did not take the matter seriously, implement effective steps or establish the facts.

Japan's Foreign Ministry declined to comment.
