Chinese Defence Minister Cao Gangchuan held talks with visiting US Secretary of Defence Robert Gates in Beijing on Monday.
The talks were expected to cover such topics as the international and regional security situation, military-to-military relations and other issues of common concern.
The military leaders were also to discuss the establishment of a military hotline between the two countries.
This is Gates' first visit to China since he was appointed Defence Secretary in December. He is the highest ranking US military official to visit the country since former Secretary of Defence Donald Rumsfeld in October 2005.
Gates, who arrived in Beijing Sunday night, is on a three-day official visit to China at the invitation of Cao. He will also meet China's state leaders and senior diplomats.
