The Chinese Foreign Ministry on Monday called for de-escalation of Russia-Ukraine conflict after recent reports of Ukrainian troops entering Russia's border region of Kursk.

In a statement, the ministry said China will continue to maintain communication with the international community and play a constructive role in promoting the political settlement of the crisis.

It added that China calls on all parties to abide by the "three principles" of de-escalation – no expansion of the battlefield, no escalation of fighting and no fanning of the flames by any party.
