About 10,000 representatives from all walks of life paid silent tribute to thousands of victims of the 1937 massacre as sirens howled over the eastern city of Nanjing in Jiangsu Province.
Xi, 64, along with senior officials attended the ceremony held in the square of the Memorial Hall of the Victims in Nanjing Massacre by Japanese Invaders in the Nanjing city.
Japanese troops captured Nanjing, then China's capital, on December 13, 1937 and embarked on more than 40 days of slaughter.
Surprisingly Xi did not speak at the meeting, raising speculation that he did not like to upset Japan in the midst of efforts by both the countries to warm up to each other after a prolonged spat over the disputed islands in the East China Sea since 2012.

Asked whether Xi skipped speaking at the meeting so as not to upset Japan, Chinese Foreign Ministry spokesman Lu Kang told media briefing that "for me I don't see any links you have made. For China and Japan relations, it is important to learn from history so as to get our steps towards future".
Yu said the ceremony was held to honour national heroes who sacrificed their lives for victory, as well as international soldiers and friends who joined the Chinese in fighting.
"The commemoration is meant to proclaim the Chinese people's firm stance on maintaining peace and their sublime aspiration for peaceful development," he said.
"War is a mirror, which makes people better understand the value of peace," Yu said.
Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the South China Sea.
