BEIJING -- Foreign Minister Wang Yi on Friday reminded the international community of the scars left by the massacre in Nanjing in 1937.

He said that while Hiroshima is worthy of attention, Nanjing should not be forgotten and deserves even more attention.

Wang made the remarks when asked to comment on foreign leaders' visits to Hiroshima arranged by the Japanese government. A US warplane dropped an atomic bomb in Japan's Hiroshima in 1945 towards the end of the Second World War as the United States, China and other allied countries were fighting hard to end the ferocious aggression of Japanese troops.

On Dec 13, 1937, Japanese troops captured East China's Nanjing City, then China's capital, and started barbarous killing that lasted over a month. More than 300,000 Chinese civilians and soldiers who had laid down their arms were murdered and over 20,000 women were raped.

"The victims deserve sympathy," he said, "but the perpetrators could never shake off their responsibility."

On Dec 13 every year since 2014, China marks National Memorial Day for Nanjing Massacre Victims.
