The president stressed the importance of cooperation in preventing nuclear disasters. He noted that cooperation between Ukraine and Japan, primarily in the framework of the Ukraine-Japan Committee on Improving Post-Accident Emergency Response at Nuclear Power Plants, would make nuclear energy safer and become an important contribution to the future of humanity, the press service reported. Poroshenko stressed that Ukrainians understand the sorrow of Japanese people as no one else, for they lived through the Chornobyl nuclear disaster 30 years ago. Poroshenko noted that those two most terrifying man-made disasters of our time had united the two countries with mutual support. "We are grateful to Japan for constant attention and assistance aimed at transforming the Chornobyl NPP into a safe facility. We are ready to make further efforts to exchange experience in this area," reads the letter of president Poroshenko to Japan’s Premier Shinzo Abe.
