PARIS: The emerging markets of China, India and Russia have helped boost half-year profits by 29% at France-headquartered outdoor advertising firm JCDecaux.

The world's second largest outdoor ads company reports net profit increased to €105.5 million ($134m; £71m) from €81.6 million a year earlier. H1 revenue rose 13% to €945.8m on a strong performance from its transportation, street furniture and billboard divisions.

Chairman and co-ceo Jean-Charles Decaux expects revenue growth from existing operations to exceed 6% for the full year, "comfortably ahead of forecasts for growth in the world-wide advertising market".

In addition, Decaux says the emerging markets now contribute 15% of the company's revenues, double the figure three years ago.

Last week, the company signed a joint-venture agreement with BigBoard Group to boost its presence in Ukraine and Russia and in March inked a 15-year bus shelter ad contract for the centre of the Indian capital, New Delhi.
