BEIJING — China acknowledged Monday that Libyan arms dealers came to China over the summer shopping for weapons to prop up Col. Moammar Gadhafi’s faltering regime, but denied that any sales were made.

Such an arms sale would have violated a United Nations Security Council resolution passed in February, with China’s support, imposing sanctions on Libya for using force against civilians.

A statement confirmed the essence of what was revealed in purported military documents recently uncovered in Tripoli, Libya. The crumpled papers, first reported by the Globe and Mail of Toronto, were discovered in a heap of trash in the neighborhood of Bab Akkarah, home to many wealthy Gadhafi supporters.

A memo written on the letterhead of a Libyan military procurement agency says pro-Gadhafi agents flew to Beijing on July 16 and met with officials of three state-owned enterprises. The memo says the Chinese companies were eager to sell whatever they had ready and to make new weapons.
