Malaysia was optimistic about a positive outcome of the Trans Pacific Partnership Agreement (TPPA) negotiations but unwilling to be tied to a strict deadline for conclusion, Malaysian Foreign Minister Anifah Aman said Friday in Putrajaya, local media reported.

While Malaysia believed the TPPA could be good for the country, there was a limit to what "it can commit without affecting national interests and the ability to continue socio-economic developments," he said at a press conference on US President Barack Obama's upcoming visit to Malaysia, according to Bernama, Malaysia's state news agency.

"Malaysia views that a great deal of flexibility is needed to enable Malaysia to come on board in sensitive chapters," he said.

While stating that Malaysia would remain engaged in the negotiations, Anifah said "it is not a done deal yet. We need to address few issues. We need to look closely at national sovereignty and our right to decide on domestic policies."

The minister said Malaysia had a certain stand on matters like government procurement, state-owned enterprises, investor-state dispute settlements and intellectual property rights.

"Whatever is the final form, the TPPA would be debated in parliament to ensure that it is subject to full democratic scrutiny and accountability," he added.
