The US has applauded Taiwan for establishing diplomatic ties with the self-declared republic of Somaliland.
A tweet from the US National Security Council described Taiwan as a great partner.
Both China and the Somali government in Mogadishu have condemned the move which was announced at the beginning of the month.
China has in recent years been urging African nations to cut ties with Taiwan. Only Eswatini - the country formerly known as Swaziland - has retained full ties.
After years of lingering tensions, the Somali government has recently tried to improve its relationship with Somaliland which declared independence in 1991 but has not been recognised by the international community.
