Coca-Cola Co is to double its investment in Vietnam by injecting another US$200m into its drinks operations in the country over the next three years.

Coca-Cola Co chairman and CEO Muhtar Kent announced the investment plan during a visit to Vietnam late last week.

"Vietnam is a very important growth market to The Coca-Cola Co," said Kent, following a meeting with the country's prime minister, Nguyen Tan Dung.

"We have already invested more than US$200m in Vietnam and today in conjunction with our bottler we have committed to invest additionally $200m over the next three years," said Kent.

He praised Vietnam's "more positive investment environment" and economic growth in 2009 amid the global economic crisis. The country joined the World Trade Organisation in 2007.

Last month, Coca-Cola Co announced that it and its bottlers would invest $5bn in Mexico, while earlier this year the soft drinks giant also said it would inject a further $2bn into China.
