Following protests and demonstrations in Hong Kong, there were reports of greater scrutiny from mainland authorities at border crossings between the mainland and Hong Kong when the border was last open. This included reports that travellers’ electronic devices had been checked at border crossings. You should be aware that the thresholds for detention and prosecution in China differ from those in Hong Kong. See Local laws and customs and Safety and security.

China has a zero tolerance policy on drugs. There are severe penalties for drugs-related offences including the death penalty. Police often raid bars and nightclubs checking for the use of illicit substances. Raids on private homes have also occurred. Police also have the power to detain or prevent you from leaving China if you are involved in or connected to a business and/or civil dispute. See Local laws and customs and Safety and security.

Terrorists are likely to try to carry out attacks in China. Although foreigners haven’t been specifically targeted, attacks may occur in places visited by foreigners. You should take particular care during national holidays or when transiting public transport hubs, and always follow the advice of the local authorities. Previous attacks have targeted public places including on one occasion at a railway station and an open air market in 2014. There have been no recent attacks in the main tourist areas. The risk is higher in the Xinjiang Uyghur Autonomous region. You should take particular care and remain vigilant when travelling to or within Xinjiang. See Terrorism.

Do not attempt to travel to Tibet without getting the correct permits. The Tibetan Autonomous Region (TAR) can be closed to foreigners without notice. See Tibet and the Tibet Autonomous Region.

China doesn’t recognise dual nationality. If you have both British and Chinese nationality you may be treated as a Chinese citizen by local authorities, even if you enter China on your British passport. If this is the case, the British Embassy may not be able to offer you consular assistance. The FCDO has published guidance on nationality in China. If you’ve formally renounced Chinese citizenship, you should carry evidence that you have done so. See Local laws and customs.

High levels of air pollution can occur in major urban and industrialised areas in China, and may aggravate bronchial, sinus or asthma conditions.

The typhoon season in China normally runs from May to November. You should monitor the progress of approaching storms and follow the advice of the local authorities. See Natural disasters.
