Russian President Vladimir Putin held a working meeting with Chinese defense minister Li Shangfu in Moscow on Sunday, Tass news agency cited Kremlin spokesman Dmitry Peskov as saying.
Beijing had announced Li's visit to Moscow last week, saying he would meet defense officials, but made no mention of a meeting with Putin.
Peskov told Tass that details of the meeting would be released later.
Chinese President Xi Jinping met Putin in Moscow last month.
Russia and China's "no limits" partnership
Russia and China have declared a "no limits" partnership and have moved to further strengthen their economic, political and military ties since Moscow sent tens of thousands of troops into Ukraine in February 2022.
Ukrainian forces are finding a growing number of components from China in Russian weapons used in Ukraine, a senior official in Kyiv said on Friday. China has repeatedly denied sending military equipment to Russia.
