An opposition lawmaker is questioning whether Malaysian billionaire Jho Low has been dictating Malaysia's foreign policy with Saudi Arabia.

DAP's Serdang MP Ong Kian Ming raised this concern after Sarawak Report leaked email correspondence showing Jho Low and his associates laying the groundwork for Prime Minister Najib Abdul Razak's 2010 visit to Saudi Arabia.

This includes preparing letters for Najib to send to the Saudi Arabian king and drafting statements on Malaysia's stance towards Saudi Arabia's military actions.

"Firstly, a close associate of Jho Low, Seet Li Lin, is alleged to have prepared the draft of a letter to be sent by Najib to the then king of Saudi Arabia, King Abdullah.

Secondly, Tarek Obaid, the founder of Petro Saudi, was alleged to have sent Jho Low an email on Nov 13, 2009, asking the Malaysian prime minister to support Saudi Arabia's military action in northern Yemen against a rebel group known as the Houthis.

"A draft statement was even prepared by Mr Obaid. On the 19th of November, Najib issued a statement condemning the Houthis and supporting Saudi Arabia’s right to defend itself," Ong ( above, left ) said in a statement today.

Ong also cited the allegation by Sarawak Report that Jho Low had made arrangements for Najib to be interviewed by the Al-Arabiya News Channel.

"Malaysia’s foreign policy must be dictated in the best interests of Malaysian citizens.

"The fact that an individual or a small group of individuals can dictate the foreign policy interests of Malaysia for their own personal gains, as alleged by the Sarawak Report expose, is highly disturbing.

"I call upon Prime Minister Najib to give an account of these allegations, as well as the other allegations raised in the Sarawak Report expose on Feb 28, 2015," Ong added.

Najib visited Saudi Arabia in January 2010, after initially planning for the visit to take place in December 2009.
