From National Review:

In Wolf II, China is the only powerful, responsible, and benevolent world power. Chinese workers help Africans build their economy. Chinese doctors work to discover a cure for a deadly endemic. And the film unabashedly takes several swipes at the U.S. When African and Chinese civilians inside a factory are under attack by rebels and mercenaries, the only good American in the movie, Rachel Smith, a Chinese-American volunteer, fanatically tries to contact the U.S. embassy for help. Leng asks her, “Why are you calling the Americans? Where are they? It is a waste of time.” After she tells him that she tried to reach American government by Twitter, Leng responds that “the Americans are good for nothing.”
