BEIJING — China’s Foreign Ministry admitted on Monday that state-run arms companies met Libyan officials this summer to broker arms sales to Col. Muammar el-Qaddafi’s besieged regime, apparently confirming information in Libyan government documents found by a Canadian journalist in Tripoli.

But a ministry spokeswoman denied that Chinese government officials knew of the talks, and said that no arms were delivered to the Qaddafi regime, either directly or through third parties.

“Chinese companies have not signed any military or trade contracts with Libya, let alone provided military exports to Libya,” the spokeswoman, Jiang Yu, said at the ministry’s daily briefing. “China exercises strict management over all military exports.

“Relevant Chinese government departments with responsibilities over military exports will take this matter seriously,” she said.
