evidence: Sabah Perikatan Nasional chairman Ronald Kiandee has urged the government to declassify a maritime agreement signed with Indonesia in June, in order to put to rest concern following Putrajaya's denial that the pact included the Ambalat block off the coast of Sabah. [...] "The Ambalat block, an area measuring 15,000 sq km in the centre of the disputed territory off the coast of Sabah, contains the biggest crude oil deposits in the world and has long been defended by Malaysia, meaning that it cannot be compromised at all," he said. [...] Alamin said the recent maritime agreements, hailed by both leaders as ending an 18-year dispute, had nothing to do with the Ambalat block or any other area more than 200 nautical miles from the EEZ.
