Indonesia's foreign minister says he's baffled by the latest report of a top-secret document about Australia spying on Indonesia and offering to share that information with the U.S.

Foreign Minister Marty Natalegawa says he's not sure how snooping on a trade spat could relate to security.

He said Monday he found mindboggling Australia Prime Minister Tony Abbott's explanation concerning allegations that Canberra conducted surveillance of an American law firm hired by the Indonesian government to help in a trade dispute with the U.S.

In the document obtained by former U.S. National Security Agency analyst Edward Snowden, Australia offered to share the information it collected with the NSA, The New York Times reported on its website over the weekend.

Natalegawa was speaking to reporters after meeting Secretary of State John Kerry.
