North Korea announced plans last month to launch what it says is a communications satellite from its Musudan-ri launch site in early April. However, the U.S., Japan and South Korea believe that the secretive state is planning to test its Taepodong-2 long-range missile.
"We understand that the situation in northeast Asia is currently very tense. It would therefore be better if our North Korean partners were to refrain from the launch," Alexei Borodavkin told reporters.
The deputy also said that Russia has constantly emphasized the need to avoid antagonizing the issue. "[We] need to calmly evaluate the situation without any commotion or counter threats, and all of the issues surrounding the launch should be decided through dialogue and consultations between the interested countries," he added.
The Japanese Jiji Press agency last week cited diplomats in Beijing as saying the launch would go ahead on April 4 barring adverse weather conditions or last-minute repairs.
Following the announcement Japan's Security Council on Friday gave approval to the defense ministry to destroy the North Korean rocket if Pyongyang goes ahead with the launch.
"It's important to deal with and eliminate the North Korean projectile should it threaten the people's security and safety by falling into our airspace, waters or soil," Kyodo news agency quoted Japanese Defense Minister Yasukazu Hamada as saying on Friday.
According to North Korean experts, the first stage of the rocket is due to fall in the Sea of Japan, 130 kilometers (93 miles) off the coast of Japan near the Akita Prefecture, and the second stage is due to come down somewhere in the Pacific Ocean.
Japan has deployed two Aegis destroyer vessels equipped with standard missile-3 interceptors in the Sea of Japan.
Four Patriot guided-missile units will also be deployed on the ground in the prefectures of Akita and Iwate, as well as around the capital, including the Defense Ministry headquarters near the Imperial Palace.
U.S. Secretary of State Hillary Clinton has warned North Korea that the firing of a missile of any kind would be a "provocative act" that could harm the six-party negotiations on the country's denuclearization.
The talks, involving the two Koreas, the United States, Russia, China and Japan, came to a standstill last December, over North Korea's refusal to allow international inspections at nuclear sites.
