Japan and the United States plan to boost the technical abilities of the 10 members of ASEAN to investigate cybercrimes, according to government sources.

At a time when China's military is suspected of having launched massive cyberattacks, notably against the U.S., Tokyo and Washington are eager to show their cooperation with the Association of Southeast Asian Nations to counter such moves, the sources said Saturday in Tokyo.

To that end, Japan will provide $150,000 and the United States $250,000 to the United Nations to facilitate the dispatch of anti-cybercrime experts by the U.N. Office on Drugs and Crime to ASEAN members, the sources said.
