Parliament can continue debating the Trans-Pacific Partnership Agreement after the deal has been inked, Deputy Minister in the Prime Minister's Department Razali Ibrahim said.

Razali said this when asked if the two-day special parliamentary session on the TPPA on Jan 26 and 27 is sufficient.

"Even if we sign it, the TPPA will only be fully implemented in 2018, so the debate can definitely continue.

"What's important in these two days is (to decide) whether or not to sign it.

"That should be enough. People only take one or two days to sign agreements, so this is the same," Razali said.

He also said the government would have to adopt some new policies if the agreement is signed.

"Every decision needs to be followed with decisions and rules that may be implemented by the government to ensure that what we are doing is not jeopardised," Razali said.

However, he did not elaborate what these policies would be.

The deputy minister said this on the sidelines of a TPPA briefing at his private office in Bangsar, Kuala Lumpur, last night.

About 20 people attended the briefing, which also included a strategising session.

The media was not allowed to sit in during the strategising.
