The meeting between Chinese President Xi Jinping and Russian President Vladimir Putin is a very important diplomatic moment.
Sky News Moscow correspondent Diana Magna has said that trade and economic ties are expected to be discussed, but Russia is seen as the junior partner in the partnership.
Both leaders are eager to showcase their role as peace brokers in the Ukraine conflict, with XI Jinping refraining from condemning Russia.
The Chinese government has provided little information on the purpose of the visit, but the Kremlin's website suggests important bilateral documents will be signed.
