On 6 May 2022, ahead of the celebration of the 77th anniversary of Victory in the Great Patriotic War, SCO Secretary-General Zhang Ming, together with the SCO Secretariat's delegation, heads of diplomatic missions and diplomats from the Russian Federation, the Republic of Azerbaijan, the Republic of Armenia, the Republic of Belarus, the Republic of Kazakhstan, the Kyrgyz Republic, Mongolia, the Republic of Tajikistan, the Republic of Uzbekistan, members of the Foreign Ministry of the People's Republic of China and other government bodies and Russian compatriots living in China visited the memorial complex to Soviet and Mongolian soldiers who died during the liberation of Northeast China, in Zhangbei County, Hebei province.
All delegations laid wreaths and fresh flowers at the monument and paid tribute to the fallen soldiers with a minute of silence.
Initially the monument was erected in 1945 at the burial site of the Soviet and Mongolian soldiers who died during the liberation of Zhangbei County. However, it was destroyed during the Chinese Civil War of 1945-1949. Following the proclamation of the People's Republic of China, a decision was made to erect a stately memorial, which was opened on 20 October 1957.
Names of 69 Soviet and 56 Mongolian soldiers are engraved on the central wall of the memorial.
