“When travelling abroad, you should stay vigilant, pay attention to personal safety and guarding state secrets, and refrain from participating in or assisting in any behaviour that may harm national interests while enjoying the scenery,” the MSS said on social media on Wednesday.
It said Chinese tourists abroad should not use local public Wi-fi networks to log in to important accounts or send sensitive data. It added that their personal electronic devices should be equipped with security protection measures to prevent “illegal intrusions”.
The MSS also reminded Chinese officials working in sensitive positions to carefully check whether items they take abroad contain confidential information before embarking on their trips.
“After going abroad, it is even more necessary to be aware of confidentiality discipline. You should not talk about sensitive topics and should avoid leaking sensitive information,” it added.
