BEIJING -- About 7.28 million people have been restrained from purchasing plane tickets for defaulting on court rules, according to the Supreme People's Court (SPC).

Courts, public security authorities and banks have joined hands to extended penalty restrictions to people who default on court orders. About 7.49 million defaulters have been made public, according to an SPC statement Friday.

Among them, 7.28 million were restricted from purchasing plane tickets and 2.74 million barred from traveling by bullet train or high-speed train, the statement said.

Chinese courts are adopting information technology to punish those who default on court decisions, to safeguard judicial authority and credibility.

The SPC has cooperated with airlines and railway companies since December to bar those who default from purchasing tickets, based on their identity card information and passports.
