evidence: KOTA KINABALU: The government should declassify the maritime delimitation treaty between Malaysia and Indonesia in the name of public interest, says Datuk Seri Dr Ronald Kiandee. [...] The Ambalat block measuring 15,000km per sq foot in the centre of the territories still in dispute outside Sabah’s coastal area is said to have the largest source of crude oil in the world and it has been defended by the Malaysian government for so long, said Kiandee. [...] He said several media reports claiming that Malaysia and Indonesia were working together in oil and gas exploration at the Ambalat block were also adding more concern to the issue.
