According to Xinhua, China’s naval training ship “Zhenghe” and the frigate "Mianyang" conducted joint naval maneuvers with the Australian Navy missile frigate “Sydney” on September 24.
The China naval fleet visited Australia earlier. During the visit, China and Australia achieved a consensus on multiple issues in terms of building a “harmonious sea” and maintaining regional stability and peace. The joint naval maneuvers on the sea are a concrete manifestation of that consensus.
