A spokesman for the Chinese Foreign Ministry has entered the “kill everyone in China” row instigated by a late-night network television skit in the U.S. last month – asking for a more “sincere” apology than those already issued by ABC and show host Jimmy Kimmel. The controversial remark, made by a 6-year-old boy during an unscripted segment meant to satirize the U.S. government shutdown, has sparked protests from the Chinese-American community and calls for the comedian’s resignation.
