A Caucasian American businessman gets into a cab in Beijing. At first he's relieved-- the last few taxis passed straight by him, which is not unusual-- it can be difficult for non-Chinese nationals to get a cab. But then comes an uncomfortable question from the driver: "Isn't it difficult living in a country with so many black people?"A question that highlighted another issue: while non-Chinese nationals can have trouble getting a cab, it can be even worse for those with darker skin.Project manager Kris Derban has lived in China for eight years. He long suspected that taxis were not picking him up because he is an African-American. Recently his suspicions were confirmed when he asked a driver why he had hesitated to take him. "The driver said, 'I worry Africans will run off and not pay.'"But catching a cab isn't the only problem. Another common misconception Derban has to contend with is that he is a drug dealer, he said. "I'll be with a group of friends and someone specifically comes up to ask me if I have drugs. At first I was offended. Now I tease them and say: 'No, do you have drugs?'"Derban laughs off such incidents, finding humor in the ignorance. Others have been less fortunate.Liberian student David Johnson moved to China just two months ago. He said he has already been subjected to several racist remarks. "One time I was walking down the street and someone called me a stupid black c***," he reported."Maybe it was because I was with a Chinese girl and they don't like that."
