US Treasury Secretary Janet Yellen has arrived in Beijing for high-level talks, amid growing tensions over semiconductor exports.

Yellen's visit to China is her first as treasury secretary. She will remain there through Sunday.

The meetings will reportedly touch on global issues, such as climate change and debt in emerging countries.

But semiconductors are expected to loom over the talks. The United States has been limiting exports of semiconductors to China because they could be used for military purposes.

On Monday, the Chinese government retaliated by announcing that it would limit its own exports of gallium and germanium. The rare metals are used to build semiconductors.
