The United States has issued a warning to travelers regarding new legal requirements in Hong Kong that make it a criminal offence to refuse requests from authorities to unlock mobile phones or other digital devices.

The advisory reflects growing concern over evolving security regulations in the city, where authorities have expanded their powers to access electronic data during investigations.

Travelers are being informed that failure to comply with such requests could result in legal consequences, including potential arrest or prosecution.

Officials emphasised that the updated guidance is intended to ensure that visitors understand the legal environment they may encounter upon arrival.

The warning underscores the importance of being aware of local laws, particularly those relating to digital privacy and law enforcement powers.

The development comes amid broader changes in Hong Kong’s regulatory framework, with increased focus on security and information control.

The implications for travelers include heightened scrutiny of electronic devices at border crossings and during interactions with authorities.

Experts note that such measures may raise concerns about privacy and data protection, especially for individuals carrying sensitive personal or professional information.

Travelers are being advised to take appropriate precautions and to familiarise themselves with local legal obligations before entering the territory.

The guidance forms part of ongoing efforts by the US government to provide updated travel information as legal and regulatory conditions evolve in key global destinations.

Authorities have stressed that understanding and complying with local laws remains essential to avoiding complications while traveling abroad.
