China is willing to work with Russia to deepen bilateral military cooperation, and advance Sino-Russian strategic partnership of cooperation, said a senior Chinese military officer in Beijing Monday, according to Foreign Ministry sources.

Guo Boxiong, vice-chairman of the Chinese Central Military Commission, made the remarks when meeting with Russian Defense Minister Sergei Ivanov, who is here on a four-day China visit as guest of Defense Minister Cao Gangchuan.

Guo said as an important part of the strategic partnership of cooperation between the two nations, bilateral military ties have kept strengthening in recent years.

The two armed forces have had frequent high-level visits and expanded their cooperation fields, Guo said. The security consultation system between the two sides operates well, he added.

As for the very complicated situation across the Taiwan Strait, Guo said the separatism activities of Taiwan authorities posed the biggest threat to peace and stability across the strait.

He said the Chinese People's Liberation Army (PLA) will never tolerate any attempt to separate Taiwan from China, which is a consistent and unchangeable stand of China.

Guo expressed appreciation for Russia's one-China principled stance on Taiwan issue.

Ivanov said Russia-China relations experienced remarkable progress over recent years. The military technological cooperation between the two sides continuously expanded and advanced.

He hoped the two armed forces will keep on their mutual-beneficial and friendly cooperation and exchanges.

With regard to Taiwan issue, Ivanov said Russia's one-China stance is steadfast and will not change in the future.
