On July 23, a woman surnamed Zhong from southern China's Guangzhou province visitedVietnam. At the border, the Vietnamese border staff asked Zhong to hand over herpassport and proceeded to write offensive language in it. Zhong's passport was handed to Vietnamese border staff when she was entering the border at Tan Son Nhat International Airport. 'The border staff kept my passport for around three minutes and after I got it back, I saw 'F*ck you' was scribbled on two pages where nine-dash line is printed', said Zhong, who also expressed her disappointment at Vietnamese civil servants' appalling conducts. All new Chinese passports issued from 2012 feature Chinese map printed with nine-dash line on page 8, 24 and 46. The offensive scribblings were written on page 8 and 24 of Zhong's passport. The Chinese Consulate-General in Ho Chi Minh City condemned this behavior as‘shameless and cowardly.' China has requested that a formal investigation be carried out,and that the guilty party be seriously dealt with to discourage others from repeating thebehavior. The Vietnamese side said that an investigation will be launched at a later date.
