An international seminar titled "70-Year Common Victory" was co-organized by the Communist Party of China and the Communist Party of Russia in Khabarovsk, Russia, on Saturday to mark the 70th anniversary of victory in World War II.

Liu Qibao, head of the Publicity Department of the CPC Central Committee, attended the seminar together with Ivan Melnikov, vice-chairman of the Communist Party of Russia.

In his opening speech, Liu, also a member of the Political Bureau of the CPC Central Committee, said both China and Russia, as the main battlefields during World War II in Asia and Europe, made great sacrifices and contributions to victory in the war.

The commemorative activities jointly held by the two countries reflect the two peoples' common respect for history, Liu said.

He also noted that both China and Russia, as founding members of the United Nations, share a common responsibility for safeguarding peace, security and stability in the region and the world.

Liu called on the two countries to strengthen coordination to defend the fruits of the World War II victory as well as the postwar order, firmly oppose any act of whitewashing wartime atrocities and promote the establishment of lasting peace and common prosperity across the world.

Melnikov said Russia is ready to further strengthen cooperation and coordination with China to counter any falsification of history and make joint efforts to promote global peace, development and multi-polarization.

Before the opening of the seminar, the CPC delegation presented fresh flowers at the Lenin monument in Khabarovsk with the delegation of the Russian Communist Party.

At the invitation of the Communist Party of Russia, the CPC delegation, headed by Liu, kicked off its visit to Russia on Wednesday to attend activities to commemorate the victory in the world anti-fascist war.
