The word Marxism-Leninism is used roughly as a synonym for Communism. (Marx was a philosopher who wrote about his ideas for a Communist state, and Lenin was an early leader of the Soviet Union, which was the name Russia took during its Communist period.)
China is still a Communits country, although it has evolved somewhat away from Marx's plan. Vietnam, North Korea, and Cuba have Communist systems. Various other countries at various times have policies leaning toward Communism, as Venezuela these days.
The World Trade Organization seeks to develop trade between countries. One consequence of globalization is the exploitation of developing countries' resources and labor, which a Marxist would certainly be opposed to.
