A senior Pentagon official held talks with the Chinese military for the first time since President Joe Biden took office in January to focus on managing risk between the two countries, a U.S. official told Reuters on Friday.

The United States has put countering China at the heart of its national security policy for years and Biden's administration has described rivalry with Beijing as "the biggest geopolitical test" of this century.

Relations between China and the United States have grown increasingly tense, with the world's two largest economies clashing over everything from Taiwan and China's human rights record to its military activity in the South China Sea.
