Chinese President Xi Jinping urged the European Union to continue its investments in China, taking advantage of Europe's growing fears that the U.S. is becoming an increasingly hostile trade rival to Brussels, Politico wrote.

"China expects the EU to ... share China's supersize market opportunities," President Xi said, according to state media Xinhua, in a meeting with his European Council counterpart Charles Michel in Beijing.

"[China and the EU] should jointly oppose decoupling, and jointly oppose politicization and weaponization of trade and technology. China will remain open to European companies, and hopes that the EU would reject interference and provide Chinese companies with a fair and transparent business environment," Xi added.

"We welcome Europe's continued participation," Xi added, "and continued win-win."

Michel, for his part, focused his message on Russia, saying that the EU "counts on" China to "call on Russia to respect the core principles of the U.N. Charter and contribute to ending Russia's brutal destruction and occupation," according to his spokesperson.

At the press conference, Michel said the Chinese leader assured him that China was not sending weapons to Russia. “President Xi … made it very clear China is not providing weapons to Russia. President Xi made very clear that the threat — the nuclear threat — is not acceptable.”

"On the protests, yes, we discussed that question as well, and the acceptance by the societies to measures taken by the authorities," Michel said. "For the EU the right to assembly is a ... fundamental right guaranteed by international instruments."

On trade, Michel "set out the difficulties faced by EU companies and investors" in China, stressing that "rebalancing of the trade relations" was a "key" issue for European leaders.

During his swift visit, Michel also met with Chinese Premier Li Keqiang and National People's Congress boss Li Zhanshu.
