Stoltenberg's speech is published on the NATO website.

“We should think about how to develop new rules and standards and apply them to the diffusion of new technologies, including advanced missile technologies,” the Secretary General said.

According to him, new technologies "present problems and opportunities."

Stoltenberg said that "hypersonic missiles, autonomous weapons systems and offensive cybernetic capabilities are being developed specifically for military use and these technologies can have strategic consequences."

Earlier, Russian leader Vladimir Putin said that the Strategic Offensive Arms Reduction and Limitation Treaty (START III) is the latest instrument to limit the arms race.
