Relations between Moscow and Beijing are currently at their best stage in history, but still need to constantly advance, a Russian political expert says.
Good relations are "like riding on a bike -- one should constantly move ahead and keep riding in order not to fall down," Yuri Tavrovski told Xinhua ahead of President Dmitry Medvedev's upcoming visit to China.
Tavrovski cited economic relations between the two countries as a very good example of such a "bike ride."
Russian-Sino economic and trade cooperation has a broad prospect and has maintained momentum, he said, adding that trade volume between the two countries might reach 60 billion U.S. dollars this year.
The existing mode of cooperation has been mutually beneficial, too, otherwise it would not have survived for long, he said.
Tavrovski pointed out that that the high-tech share of bilateral economic and trade cooperation will increase remarkably when Russia's bid to develop an initiative economy makes headway.
"If Russia wants to change the model of bilateral trade, we must change our economy first," he said.
Medvedev understands the situation clearly and will travel to Beijing "with his eyes wide open" to glean as much as possible from China's modernization experience, Tavrovski said.
"We may study the experience of Hong Kong and Shanghai transformation, push forward the idea of regional reserve currencies, revive the projects of rapid railways and highways linking Europe to China via Moscow, and develop tourism," he said.
Tavrovski spoke positively of Sino-Russian energy cooperation.
Through ever expanding cooperation in energy, Tavrovski said, Russia could avoid being overly dependent on the Western market and China could reduce its dependence on supplies from the Middle East, the expert said.
There are problems in bilateral energy cooperation, Tavrovski said, but they were purely commercial, not political, issues.
China, he said, "has been very important for Russia as a political and economical counterweight to the West."
Neither Russia nor China treat each other as competitors "because Russia has been descending while China has been ascending, whatever respect to take," he said.
