The United States, South Korea and Japan have agreed to launch a high-level consultative group on countering North Korean cyber activities that they say finance its unlawful weapons programs, South Korea’s presidential office said on Monday.

Anne Neuberger, U.S. deputy national security adviser for cyber and emerging technologies, held talks with her South Korean and Japanese counterparts in Washington last week. They agreed to hold quarterly meetings under the new framework, the presidential office said.

“It is aimed at strengthening the three countries’ effective response capabilities against global cyber threats, including jointly countering North Korea’s cyber activities that are abused as a key source funding its nuclear and WMD programs,” the office said in a statement.
