MEXICO CITY (AP) _ Cuba reported Monday that a former top economic official has been removed from the Communist Party Central Committee.

A dispatch from the official Cuban news agency Prensa Latina said the action was taken after a critical report about Humberto Perez Gonzalez was read at the party congress, which ended last Friday.

He was identified as former president of the central planning committee and former vice president of the Council of Ministers executive committee.

Prensa Latina quoted the official newspaper Granma as saying a committee was formed to investigate Perez's responsibility for ''erroneous conceptions and practices that were found in the planning of the national economy.''

Until 1985, Perez led a major agency of Cuba's economic planning commission. The agency said the official newspaper referred to a ''lack of control'' at the agency and its tendency toward ''provoking detours.'' It did not elaborate.

At last year's party congress, President Fidel Castro said Cuba faced economic hardship and called on the party to lead the way toward ending corruption and improving worker discipline.
