Mainland tourists warned of risks in South Korea travel

China's top tourism authority has warned tourists of the risks regarding South Korea's change of its entry policy for Chinese citizens.

"The number of incidents involving Chinese citizens' entry to Jeju Island of South Korea has risen sharply recently. Some of them were denied entry and waited a long time at airports before they were repatriated, which has attracted wide public attention," said a statement on the website of the China National Tourism Administration on Friday.

It said the administration attached great importance to the matter.
