Russian Defense Minister Sergei Shoigu met Tuesday with Air Force General Xu Qiliang, deputy vice chairman of China's Central Military Commission, and other regional military officials as part of the Shanghai Cooperation Organization (SCO) summit in the eastern city of Qingdao. As increasingly powerful Russia and China built up their clout on the world stage, they sought a more united front against the US, which frequently challenged their rise.

"Time changes everything," Shoigu said, according to the Russian Defense Ministry. "But, fortunately, it does not change our relations both personally between us and between our states, and the very close, friendly relations of the heads of our states serve as a guarantee of this."

Shoigu praised "the privileged character of intergovernmental ties" evidenced by numerous meetings between Russian President Vladimir Putin and Chinese President Xi Jinping, both of whom secured enough national support to extend their terms last month. He said the two nations were continuing "their strategic course toward further boosting friendly and trustworthy ties in the defense sphere," calling this relationship "an important factor for maintaining global and regional security."
