China is considered the most-promising emerging market in which to invest by Bloomberg LP, a global financial data provider, for the third consecutive year.

The country has topped the list since Bloomberg started the rankings in 2012.

Among Brazil, Russia, India and China, known as the BRICs, China is the only market to reach the top 10 of the 22 emerging-market countries ranked by Bloomberg, which announced the result on the weekend.

The Bloomberg rankings are based on 19 measures of the investing climate, from forecasts of gross domestic product growth for the next two years to the ease of doing business. Its promising GDP growth rate, which Bloomberg predicted to be 7.4 percent for 2014 and 2015, is a major reason China won the top spot.

"China is going to continue to grow, although at a slower pace than in the past," said Mark Mobius, who oversees $53 billion in assets as chairman of Templeton Emerging Markets Group. "The reform process is going to result in more volatility."

China fared poorly, however, in the "the ease of doing business" category, ranking only 96th out of all economies.

Two other Asian nations closely followed China in the emerging-markets ranking, with South Korea second and Malaysia at third.
