The Chinese foreign minister has arrived in Addis Ababa for an official visit to Ethiopia as western nations urge their nationals to leave the Horn of Africa country over the escalating conflict in the north.
Ethiopia's Deputy Prime Minister Demeke Mekonnen welcomed the Chinese foreign minister on arrival at the airport.
In the absence of Prime Minister Abiy Ahmed, who is at the frontline leading the fight against rebels loyal to the Tigray People's Liberation Front (TPLF), Mr Wang is expected to hold discussions with Mr Demeke.
China has previously highlighted its opposition to external "meddling" in the internal affairs of Ethiopia as the latter faces growing pressure from the US and some European countries over the conflict in the north and a worsening humanitarian crisis.

Richard Moore, known as "C", warns of China data and debt traps and the need for a robust UK response.
China's President Xi Jinping has promised to send to Africa some one billion Covid vaccine doses to help close the "vaccination gap".
The president made the pledge during the China-Africa summit.
Out of the one billion, 600 million doses will come from China directly while 400 million will come from other sources like funded production sites.
China has already been giving doses to African countries.
The recent pledge comes amid the spread of the new Omicron coronavirus variant that was first detected in southern Africa.
