Concerning the recent incidents where Chinese nationals causing brawls in foreign airports, the Chinese Foreign Ministry has called for maintaining rationality. Maintaining rationality should be practiced by overseas Chinese business people who have been walking on the edge of "gray areas" for years. If the incident happened in the gray area, they cannot expect to receive help from the Chinese military. The Chinese military can only involve in evacuation and transportation, and cannot be more deeply involved in protecting the people. Under the impact of the conservatism, the crackdown on Chinese "gray economy" around the world is about to begin soon.
