During a negotiation between the Chinese group and the U.S. group, one of the Chinese negotiators insisted that the American project in Thailand had some problems and the technology didn’t work well. The American negotiator, who was quite familiar with Chinese culture, didn’t say anything for explanation. Instead, he called the head office and asked the office in Bangkok to check there was no problem. The next day, at a private dinner meeting, the American negotiator told the Chinese manager that his statement about Thailand was not correct, but he did not mention anything related to what he had said at the previous meeting. He gave him the telephone number of the Thai counterpart and asked him to check for himself. After that, the Chinese manager became very friendly and helpful to the American company.Question: Why didn’t the American manager explain directly?
