China’s capital has banned outdoor advertising that promotes hedonistic or high-end lifestyles as the government seeks to ease public concerns about the country’s widening wealth gap.

The Beijing Administration for Industry and Commerce said in a recent statement that businesses were given an April 15 deadline to rectify such ads, along with any that excessively promote “foreign” things.

It gave no details on which “foreign” things were deemed objectionable.

Such promotions help create a politically “unhealthy” climate, it said.

Violators could face fines of up to 30,000 yuan (€3,250), the state-run China Daily said yesterday.

Newly forbidden words include “supreme”, “royal”, “luxury” or “high class”, which are widely used in Chinese promotions for houses, vehicles and wines, it said.

Authorities in the southwestern megacity of Chongqing last week issued similar rules that barred real estate advertisements from using phrases including “best”, “unique” or “irreplaceable”.

Chinese officials are struggling to cool criticisms over a widening income gap at a time when high inflation has put economic pressure on the country’s hundreds of millions of low-income farmers and industrial workers.

Premier Wen Jiabao said earlier this month that “resolving unfair income distribution” would be a major objective under a 2011-2015 state economic plan. The brokerage firm CLSA Asia-Pacific Markets predicted in January that China would become the world’s largest luxury goods market by 2020, accounting for 44 per cent of worldwide sales and bigger than the entire global market is now.
