What they say

It is important to remove existing obstacles, such as trade protectionism and the frequently launched trade remedy measures, in international trade. It would also be helpful to facilitate exchanges, reduce trade costs and improve infrastructure. In addition, a multilateral investment deal would be useful to make it easier to invest in developing countries.

Reform in infrastructure could be a key to mitigating the global economy's challenges. Infrastructure has the potential to deliver strong productive gains across all kinds of countries - least developed, emerging and developed. Furthermore, China's Belt and Road Initiative creates fresh opportunities for regional trade cooperation.
