More than 30 landlocked developing countries – from Bolivia to Bhutan and Burkina Faso – face some of the world’s highest trading costs, deepest poverty and weakest investment flows.

Rebeca Grynspan, head of the UN’s trade and development agency, UNCTAD, has told UN News that they are "invisible to much of the world", prisoners of outdated structural constraints.

Speaking on the sidelines of the Third UN Conference on Landlocked Developing Countries, in Awaza, Turkmenistan, she explained to Nargiz Shekinskaya why digital trade, regional integration and long-term investment are critical to unlocking their potential.
