Chinese President Xi Jinping on Tuesday lauded the cooperation between China and Central and Eastern European Countries (CEEC), saying that "17 plus 1 could make more than 18."

Xi made the remarks while delivering a keynote speech at the China-CEEC Summit held via video link.

China-CEEC cooperation is based on mutual respect and has no political strings attached, Xi said, adding that all countries involved, regardless of their size, are equal partners in a cooperation mechanism featuring extensive consultation, joint contribution and shared benefits.

"Guided by the conviction that '17 plus 1 could make more than 18,' we have set up a multidimensional cooperation framework led by the leaders' summit and covering 20-plus sectors to ensure the participation of all CEE countries," he said.

"Mindful of each other's concerns, we have drawn up plans and decided on projects based on the national reality of each country, and encouraged all countries to find the best way to leverage their respective strengths in cooperation," he said. 

The cooperation between China and CEEC has developed some principles that are reflective of its distinctive features and accepted by all parties, Xi noted.
