Cuban Vice President Carlos Lage has told the annual summit of the Non-Aligned Movement that the world is becoming more unjust as one nation dominates by applying economic and political pressure on others.
Cuban state media quote Lage as blaming a "hegemonic power," but he did not say which country he meant. Other news reports say he singled out the United States.
Cuba is hosting the six-day summit in its capital, Havana, as President Fidel Castro remains in seclusion after health problems in July. Various other Cuban officials are appearing at the summit.
A spokesman for United Nations Secretary-General Kofi Annan says the U.N. chief will speak at the summit on Friday. Mr. Annan is expected to talk about the role of developing nations in the changing dynamic of international relations.
The Non-Aligned Movement formed in 1961 during Cold War tensions between the Soviet Union and the United States. It includes more than 100 nations not aligned with any major power bloc.
