US-China cooperation on cybercrime has stalled since the US indictment of Chinese officials on hacking charges, while Chinese hacking efforts have continued unabated, Reuters reported, citing comments from a senior US security official on Thursday. In May, the Justice Department charged five Chinese military members with hacking US companies to steal trade secrets, prompting Beijing to suspend a Sino-US working group on cyber issues including money laundering, child pornography and drug trafficking. The indictments, the first criminal hacking charge the US has filed against specific foreign officials, strained US-China commercial relations and created troubles for US technology companies in China.
