He stressed that Beijing has repeatedly spoken about its position.
"The Navalny case is exclusively an internal affair of Russia, external forces have no right to interfere," RIA Novosti quotes the diplomat.
On March 2, the European Union imposed new sanctions against Russia due to the situation with Navalny.
On the same day, the United States also announced new restrictive measures against Moscow.
Russian Foreign Ministry spokeswoman Maria Zakharova called the new US and EU sanctions an attempt to divert attention from her own problems.
