BEIJING (TIP): Chinese authorities have blacklisted four people for misbehaving while traveling, as Beijing seeks to improve the image of its tourists who are visiting the world’s touristy spots in increasingly large numbers but also are earning a reputation for rudeness.

The four blacklisted this week by the China National Tourism Administration include a woman who poured instant noodles soaked in hot water onto an AirAsia flight attendant and made insults and threats at the attendant. Her male traveling companion was also blacklisted after getting into an altercation with the attendant. Their behaviors necessitated the flight returning to Bangkok.

Zhang Yan and Wang Sheng were the first two people to be blacklisted by the national agency under a rule that took effect in April.

It allows authorities to blacklist a person for unruly, disruptive, disrespectful or illegal behaviors on travel and to notify police, customs, border security, transportation agencies and credit agencies.

No punishments are specified but the blacklisting means people could see their travel plans affected during a specified timeframe.

The third person on the blacklist forcibly opened emergency doors on a domestic flight and was detained 15 days. The tourism administration said he should be blacklisted for two years.

The fourth one climbed onto statues of revolutionary soldiers for taking photo, drawing widespread condemnation, the tourism administration said. He would be sanctioned for 10 years.
