Tokyo - The WikiLeaks website published documents on Friday that it says shows the US government spied on Japanese officials and companies.

The documents include what appear to be five US National Security Agency reports, four of which are marked top-secret, that reveal internal Japanese discussions on international trade and climate change policy.

A notation on one of the top-secret reports on climate change before the 2008 G-8 summit is marked for sharing with Australia, Canada, Great Britain and New Zealand.

It’s not clear if it was actually shared.

WikiLeaks also posted an NSA list of 35 Japanese targets for telephone intercepts including the Japanese Cabinet office, Bank of Japan officials, Finance and Trade Ministry numbers and fossil fuel departments at Mitsubishi and Mitsui.

The Japanese government had no immediate response.

WikiLeaks has released similar reports of US spying on Germany, France and Brazil.
