A classified government document, containing telephone conversations between South Korean and U.S. presidents, was leaked by Chinese hackers, an opposition lawmaker said Saturday.
"I received a report from the National Intelligence Service that a secret document written by the South Korean foreign ministry ahead of the Group of 20 (G-20) Summit in London in April 2009 was leaked to China," Rep. Shin Hak-yong of the main opposition Democratic Party said.
The document, titled "plans for London G-20 Summit," includes the government's positions and strategies for the international event as well as related intelligence collected by overseas Korean missions, the legislator said.
It also contains a transcript of telephone conversations between South Korean President Lee Myung-bak and U.S. President Barack Obama that took place around that time, he said.
"There were no diplomatically sensitive details in the conversations... but what matters is the fact itself that a secret government document was hacked," he said.
