Speaking from Geneva, Switzerland, where he is attending the United Nations Human Rights Council, Cde Chinamasa said the big powers have compromised the international court by using it in a discriminatory manner to punish leaders from developing countries.
He said Zimbabwe rejects the acceptance of homosexuality and the legalisation of such acts through the new constitution.
In an address he made at the beginning of the meeting, Minister Chinamasa blasted those who have imposed sanctions on Zimbabwe urging them to remove them without further delays.
On Syria, Cde Chinamasa said Syrians should be given a chance to deal with their own issues without external interference.
He criticised Western powersâ€™ interference in Third World countries and cited Libya which was destroyed as a result of such meddling.
The second part of the discussions of the UN Human Rights Council started this Thursday afternoon where representatives of the various member states are expected to speak on the state of human rights in their countries.
Cde Chinamasa is expected to address the session this Thursday evening.
The first phase of the review process began in October last year when Zimbabwe was given 177 recommendations to improve the state of the human rights in the country.
Zimbabwe adopted some, put others under consideration but rejected some such as rights of gays and lesbians.

The Council is made up of 47 UN member states which are elected by the UN General Assembly.
The Human Rights Council replaced the former United Nations Commmission on Human Rights.
