President Vladimir Putin told President Xi Jinping on Monday that Russia was open to discussing China's proposals to end the fighting in Ukraine at the start of talks in the Kremlin.

"We are always open to negotiations," Putin told Xi, who was on his first visit to Moscow since the start of Russia's military intervention in Ukraine last year.

"We will certainly discuss all these issues, including your initiatives which we treat with respect, of course," Putin said.

Shortly after landing at Moscow's Vnukovo Airport, Xi said his three-day visit would give "new momentum" to Chinese-Russian ties.

He was greeted by Deputy Prime Minister Dmitry Chernyshenko on a red carpet as a military brass band played the countries' anthems, Russian state media showed.

During his initial meeting with Putin, Xi hailed "close ties" with Russia and the Russian leader said the two countries had "plenty of common objectives and tasks".

The two will continue talks on Tuesday.

The two leaders are due to discuss China's 12-point position paper on the Ukraine conflict, which includes a call for dialogue and respect for all countries' territorial sovereignty.

Putin has welcomed Beijing's statements on Ukraine as being indicative of a willingness to play a "constructive role" in ending the conflict.

But Kyiv on Monday reiterated calls for Russia to withdraw its forces from Ukraine. (AFP)
