As scheduled, Xi will attend relevant events commemorating the 70th anniversary of Russia's victory in the Great Patriotic War including the Parade on Red Square, laying wreaths at the Tomb of the Unknown Soldier, and a welcome banquet.

"President Xi Jinping's trip to Moscow is to safeguard peace and jointly create the future and also to comprehensively advance China-Russia relations," says Cheng.

After his five meetings with Putin, Xi will meet his Russian counterparts at least five times this year. Cheng says the frequent meetings with them have enabled high-level, stable development in the comprehensive bilateral partnership.

Cheng says Xi will also hold talks and meetings with Putin and Prime Minister Dmitry Medvedev respectively, as well as meet with representatives of WWII Russian veterans and representatives of Russian aid experts for China and their families. Both sides will also sign cooperation documents covering energy, aerospace, taxation, finance, investment and other fields.

"I believe President Xi Jinping's Moscow trip will surely achieve complete success and inject new and powerful impetus into the high-level development of the bilateral comprehensive strategic partnership, thus boosting common development and revitalizing both countries as well as maintaining global peace and stability," he says.

Kazakhstan is the place where Xi made public the Silk Road Economic Belt initiative in September 2013. And in October that year, Xi raised the proposal of the 21st Century Maritime Silk Road initiative in Indonesia.

Xi has left for Kazakhstan on May 7th for his second visit to this country.

Xinhua has cited Aidar Amrebayev, head of the Institute for World Economy and Politics under the Foundation of the First President of Kazakhstan, saying Xi's visit to Kazakhstan following Nazarbayev's re-election as the head of state shows support to the Central Asian nation.

"This indicates that China attaches great importance to its ties with Kazakhstan and supports its stable and sustainable development," Amrebayev says in an interview with Xinhua.
