This is the opinion of the head of the IAEA, Rafael Grossi. He said this while speaking at the Carnegie Endowment in the United States on Friday.
Grossi said that Russia is the main supplier of nuclear technologies, and China is also actively working in this area.
"This is a problem for America. She has traditionally been a leader, she has lost these leadership positions," Grossi said.
"But I heard that the head of the Ministry of Energy said that they want to regain leadership positions," the IAEA Director General added.
