The United States Vice-President Kamala Harris has arrived in Tanzania on the second leg of her first tour to Africa.

She will meet President Samia Suluhu where she is expected to raise the issue of Tanzania's non-alignment over the war in Ukraine.

The US has been keen to get more countries to condemn the Russian invasion.

Correspondents say the US Vice President's tour comes at a time of growing competition for influence in Africa by global powers such as China and Russia.
