Chinese Vice Premier Liu He and Valdis Dombrovskis, the executive vice president of the European Commission and European commissioner for trade, discussed the China-EU investment agreement on Friday.
The video conversation resulted in "constructive communication... over ways to push forward the negotiations," according to China's state news agency Xinhua.
In late October, China's Ministry of Commerce said it would be willing to make concessions so the talks could be finalized "within a year."
