China and the United States have clashed in recent months over trade, tariffs and geopolitical issues including Taiwan, the self-ruled island claimed by Beijing.

US President Donald Trump met with counterpart Xi Jinping in Beijing in May, seeking to stabilise ties, but the two countries have continued to spar over issues such as US tariffs and sanctions on China's top tech companies.

"Building a constructive relationship of strategic stability is not just a slogan; it requires action, moving towards each other and persistent efforts," Wang told Rubio in a phone call on Tuesday, according to Chinese state broadcaster CCTV.

In June, China imposed export controls on 10 US companies involved in defence and rare earth mining in response to Washington's blacklisting of Chinese tech giants for allegedly aiding the Chinese military.

Wang told Rubio that "both sides should... narrow the list of problems and manage various risks and hidden dangers".

The issue of Taiwan, he added, has "far-reaching implications".

"We hope the US will treat Taiwan-related matters with utmost caution," Wang said during the call.

Taipei relies heavily on Washington's support to counter growing pressure from Beijing, which has ramped up military drills around the island in past months.

US Secretary of State Marco Rubio said this month a proposed $14 billion arms package to Taiwan was "under review".
