UNITED NATIONS, Nov 21: Mexico’s outspoken ambassador, removed for his anti-American comments, said on Thursday night that he would resign his post a month earlier.

Talking to reporters following a UN Security Council meeting on Thursday in which he told the council members that it would be his last session, Ambassador Adolfo Aguilar Zinser said, “today I will present my resignation as ambassador of the United Nations.”

Mr Zinser had told reporters it was impossible for him to stay in his post until Jan 1, as the government wanted, after President Vicente Fox chastised him for saying the United States regarded Mexico as a second-class country.

The controversy began when Aguilar Zinser last week told university students in Mexico City that Washington wanted a “relationship of convenience and subordination” with Mexico. “It sees us as a backyard,” the ambassador said.
