The US and Chinese militaries held "frank and constructive" talks on maritime security this week, the Chinese navy reported, quoted by "Reuters".
The two superpowers are gradually restoring communications with each other after several months of trade tensions.
According to the People's Liberation Army Navy, the working-level meetings were held from November 18 to 20 in Hawaii.
Previously, US and Chinese military representatives held talks in April - this was the first such working-level meeting on military issues since the beginning of US President Donald Trump's second term. The talks, held twice a year, are known as the Naval Consultative Agreement Working Group.
"The two sides held a frank and constructive exchange of views on the current maritime and air security situation between China and the United States," the Chinese navy said.
Beijing has criticized the US freedom of navigation operations. They often take place in the Taiwan Strait and the South China Sea, international waters over which China claims sovereignty.
"China resolutely opposes any violation and provocation", the Chinese navy said, referring to the transit of US forces by sea and air.
The two sides also discussed "typical cases of naval and air encounters between the two armies to help the frontline naval and air forces of China and the US interact more professionally and safely", the statement added.
US Defense Secretary Pete Hegseth expressed concern about Chinese activity in the South China Sea and around Taiwan during a meeting with Chinese Defense Minister Dong Jun last month.
China has been steadily increasing the deployment of air, naval and coast guard forces around democratically-ruled Taiwan, which it considers its territory. The Taiwanese government rejects China's claims to sovereignty over the island.
The Pentagon has pushed for improved communication with China about its military modernization and regional posture, and has called for greater transparency about its nuclear weapons buildup and more discussions with military commanders.
The working group will hold a follow-up meeting in 2026.
