Airport Customs in Dalian in Liaoning Province seized 31 million undeclared Japanese yen in the first quarter of this year, according to a Customs official.

　　The figure is twice the amount for the same period last year and two-thirds of the total amount for 2002, the official said. More than half of the illegal money was carried by Japanese passengers. The number of Japan-based Chinese students illegally bringing in huge amounts of cash also increased.
