President Jammehâ€™s statement comes amid increasing pressure from the international community on African states to respect gay rights.
Speaking while swearing in 15 ministers of the new government, Mr Jammeh said African nations should not build their societies based on outside dictates and principles.
In the Gambia, homosexuality is punishable by up to 14 years imprisonment, for men and women.
In 2008, Jammeh gave an ultimatum to homosexuals to leave the country and vowed to “cut off the head” of any homosexual found in the Gambia.
United Nations Secretary General, Ban Ki-Moon, recently told leaders at an African Union summit that they must respect gay rights.
