Yes — as with India, this is an important difference from many other countries on our guides. Chinese passport holders currently need a full UK visitor visa arranged in advance; the lighter Electronic Travel Authorisation (ETA) available to nationals of countries like the USA, Canada and Australia does not apply to Chinese citizens. A standard visitor visa application typically requires an online form, a fee, supporting documents and a biometric appointment at a visa application centre, and processing can take several weeks, so apply well before your planned travel dates. Requirements and processing times change, so always check the current official guidance on the UK government website as early as possible.
