Mao discusses the assassination of Dr. Martin Luther King Jr. and connects the struggles of Black Americans to the struggles of oppressed people around the world. He calls for people around the world to unite against American imperialism.

At the request of Robert F. Williams, a former NAACP leader who fled to Cuba, Mao condemns racism against black Americans in the United States. He discusses several notable events in the American civil rights movement, from the Little Rock Crisis of 1957 to the then-upcoming March on Washington, and calls on "enlightened people of all races around the world" to support the struggle of black Americans.
