BEIJING, May 10 (Xinhua) -- China will make efforts to build a new image of "cultural China" to promote the country internationally, according to a ministerial plan on cultural reform and development during the 12th Five-year Plan period (2011-2015).

By the end of 2015, China will set up 25 to 30 overseas Chinese culture centers to strengthen cultural exchanges with people abroad and promote the Chinese culture, according to the plan published by the Ministry of Culture on Thursday.

The document also mapped out the ministry's future measures to promote the country's cultural industry, public cultural services, cultural heritage protection and the supervisory system in this sector.
