BEIJING, China (CNN) -- Four members of a Christian group from the United States are refusing to leave an airport in China after authorities confiscated their 300 Bibles, the group's director said Monday.

The four members of Vision Beyond Borders -- based in Sheridan, Wyoming -- arrived in the southwestern Chinese city of Kunming on Sunday. Customs officials discovered the Bibles during an X-ray scan of their luggage, said Pat Klein, director of the group, which supplies Bibles and other Christian material to people in China and other countries.

Under Chinese law, it is illegal to bring printed religious material into the country if it exceeds the amount for personal use. The group distributes the Bibles through a local shop owner in Kunming, according to Klein.

Klein said he's been bringing Bibles into China for 21 years and had no idea he was breaking Chinese law.

The group spent the night at the airport, and Chinese customs officials told them they had broken the law and repeatedly asked them to leave the airport, Klein said. He said the customs agents have not been antagonistic.
