SOFIA, Nov. 22 (Xinhua) -- A memorandum on the establishment of a China-Central and East Europe (CEE) research center for transportation infrastructure construction and investment cooperation was signed here on Wednesday.

Representatives of 11 Chinese and Bulgarian organizations such as the Sofia-based University of Transport, Bulgaria's National Railway Infrastructure Company, and China's Ningbo University of Technology, Ningbo Municipality, as well as the Secretariat for Cooperation between China and CEE countries inked the founding document.

"I am convinced that it will be beneficial for both countries," said Zanchev.
