China and Russia have vowed to strengthen global strategic stability in a joint statement signed by Chinese President Xi Jinping and his Russian counterpart Vladimir Putin on Saturday, which experts say showed their wide consensus against US "hegemony."

In the joint statement, the two sides voiced concern over increasing "negative factors" affecting global strategic stability, the Xinhua News Agency reported.

Some countries and military-political alliances seek decisive advantage in military and relevant technology, so as to serve their own interests through the use of force or threat to use force in international affairs. Such a policy has resulted in an out-of-control growth of military power and has shaken the global strategic stability system, the joint statement said.

Wu Enyuan, a research fellow at the Chinese Academy of Social Sciences, told the Global Times that the "it shows that Russia understands our core interests and it is very important for China to gain support from such an influential country."

"Moreover, China's support also provides timely help for Russia, as its economic and trade development face serious difficulties," said Wu.

Wu added that it is meaningless to discuss whether China and Russia has formed an ally. The US has formed a gang to block us in terms of politics, economy and culture.

"Facing such situation, we need seek help. Attention should be paid to the mutual support of the two countries on their core interests," added Wu.

Wang Haiyun, a former military attaché at the Chinese embassy to Russia, told the Global Times that "the joint statement shows that China and Russia have reached a wide consensus on maintaining global strategic stability against US hegemony."

As China's strategic coordination partner, Putin called for more cooperation in trade, energy, high technology, security and people-to-people exchanges, as well as synergizing the construction of the Eurasian Economic Union and the Belt and Road initiative.

 Xi and Putin also witnessed the signing of 30-plus cooperation deals, covering such areas as economy and trade, foreign affairs, infrastructure, technology and innovation, agriculture, finance, energy, media, the Internet and sports.

"Political cooperation between the two countries is good, but economic and trade cooperation is less than satisfactory," Xia Yishan, a research fellow of Central Asian studies at the China Institutes of International Studies, told the Global Times.

Xia added that economic and trade cooperation between the two countries has just begun.

"In the future, the two will deepen their cooperation on oil refining and high-speed rail construction," said Xia.
