Honda Motor Co. said Wednesday it will boost overseas production to meet growing demand for its energy-efficient cars and other vehicles, concentrating on global growth amid declining domestic sales.

Japan's second-largest automaker by sales said it plans to build a second factory in Thailand to double production capacity to 240,000 vehicles a year, President Takeo Fukui told a midyear news conference at the company's headquarters in Tokyo.

Honda, the maker of Accord and Fit cars, will spend 23 billion yen on the Thai factory. It is expected to start production in the latter half of 2008.
