BEIJNG -- China will target a bigger role in international affairs after recent successes in global diplomacy, according to a blue book published by the China Institute of International Studies (CIIS) Thursday.

"The International Situation and China's Foreign Affairs (2015)" particularly highlights the two major summits China hosted in 2014, as well as its proposals to boost Asian infrastructure with the Silk Road Economic Belt and 21st-Century Maritime Silk Road projects.

"Last year, China played a significant role in multilateral diplomacy and contributed to solving international issues," said Chen Xulong, head of the Department for International and Strategic Studies of the CIIS, referring to the Shanghai-hosted Conference on Interaction and Confidence Building Measures in Asia and the Beijing-hosted Asia-Pacific Economic Cooperation.

"The international community will stipulate an agenda this year to discuss post-2015 development," said Ruan Zongze, vice CIIS president. "China will continue to focus on peaceful development and practice this in its foreign policy."

An English version of the blue book will be published next month.

The CIIS is the think tank of China's Ministry of Foreign Affairs.
