It looks like the Kim regime received their talking points straight from Beijing:

North Korea on Monday denounced a United States decision to help build nuclear-powered submarines for Australia as an “extremely undesirable and dangerous” move that can trigger off a nuclear arms race.
The North will also take “corresponding counteraction in case it has even a little adverse impact on the security” of the country, the foreign news section chief of the North’s foreign ministry told the official Korean Central News Agency.
The United States on Wednesday announced the launch of a new trilateral security partnership with Australia and Britain, and said the countries will also work to equip Australia with “conventionally armed” nuclear submarines.
“These are extremely undesirable and dangerous acts which will upset the strategic balance in the Asia-Pacific region and trigger off a chain of nuclear arms race,” he was quoted as saying in the KCNA.
