The Obligation to Notify: Vienna Convention and Chinese Law
When a foreign national is arrested or detained in China, two legal instruments govern consular notification: the Vienna Convention on Consular Relations (VCCR), Article 36 [CN official], to which China is a party, and China's own Criminal Procedure Law, Article 85 [CN official]. Together, they create a legal obligation on Chinese authorities to inform the detainee's consulate — but implementation varies in practice.
What the Vienna Convention Requires
Article 36(1)(b) VCCR provides that competent authorities must, without delay, inform the consular post if a national of the sending state is arrested, imprisoned, or detained. The detainee must be informed of this right. Consular officers have the right to visit, communicate with, and arrange legal representation for the detained national. "Without delay" is generally interpreted as 24–72 hours.
What Chinese Law Adds
CPL Article 85 requires family notification within 24 hours, and for foreign nationals, consular notification follows the same timeline. The Public Security Bureau (PSB) handles notification, typically routed through the provincial Foreign Affairs Office to the relevant consulate general. The notification will include the detainee's name, nationality, and the detaining authority — but not detailed offence information.
What Families Should Do Immediately
(1) Contact the relevant consulate in China and provide the detainee's full name, passport number, date of birth, and any information about the detaining authority; (2) Request consular visitation; (3) Ask the consulate for a list of English-speaking criminal lawyers — and then engage one directly; (4) Understand that the consulate cannot provide legal defence, negotiate with prosecutors, or secure release — these are the lawyer's role.

Special Issues: Dual Nationals and Sensitive Cases
China does not recognise dual nationality. A person holding both Chinese and foreign citizenship will be treated exclusively as Chinese — and consular access will be denied. In cases involving national security, state secrets, or terrorism, consular visits may be restricted, delayed, or subject to conditions not disclosed to the family.
Primary legislation: Vienna Convention on Consular Relations, Article 36 [CN official]; Criminal Procedure Law, Article 85 [CN official]
