Prime Minister Shinzo Abe and Turkmenistan President Gurbanguly Berdimuhamedov agreed Friday to cooperate on infrastructure development and natural gas plant projects totaling ¥2.2 trillion in the resource-rich Central Asian country.

Abe and Berdimuhamedov also agreed to urge North Korea to follow United Nations Security Council resolutions banning the development of nuclear weapons, and affirmed tie-ups in human resources development in Turkmenistan for advanced industries using Japanese-style engineering education, according to a joint statement issued after their meeting in Ashgabat, the capital.

Given that Turkmenistan has the world's fourth-largest natural gas reserves, the leaders welcomed participation by Japanese companies in building gas processing and chemicals plants, the statement said.
