Temasek Holdings Pte Ltd remains optimistic about investing in China because the country remains one of the most promising opportunities in the world, the company said at a news conference on Tuesday.

Apart from involvement in China's banking sector, the Singapore state investor said it will also increase investment in China's State-owned enterprises and other projects related to the country's urbanization process.

According to Temasek's annual report for the fiscal year 2013 released last week, China remains the most important foreign investment destination for the company, accounting for 23 percent of its total investment after the Singapore market, where the proportion is 30 percent.
