No shouting, no fighting, no extortion – these are new guidelines for Chinese travellers abroad covering a wide range of dangerous or problematic behaviour to help head off trouble.

Travellers are told to avoid drawing attention to themselves, respect local customs and keep a wary eye on strangers.

The guidelines, on the website of the Foreign Ministry, advise travellers to keep peaceful in public places, don't talk loud and avoid sticking out.

The suggestions also advise tourists to not get involved in other people's quarrels in public places, a nod to the Chinese habit of gathering in large crowds to observe or even take part in others' arguments and fights.

Along with the booming economy, Chinese people have become a major presence in international tourism in recent years.

The number of Chinese people who travel outside their homeland each year is expected to nearly triple to 100 million by 2020.
