It is too premature to analyse the impact of Donald Trump's victory at the US presidential election on the Trans-Pacific Partnership Agreement (TPPA), said Industry and Trade Minister Mustapa Mohamed.

He said Trump's anti-TPPA could just be campaign rhetoric, which would not materialise once he is sworn in as president.

"He has made many campaign statements and some view this only as a rhetorical campaign to fish for votes.

"There are views that he would change his stance once he starts duty as president.

"My view is that the changes (Trump will bring to US policy) will not be radical, not as radical as what we have heard (in his campaign)," the minister told reporters at the Parliament lobby.

Mustapa added Trump had throughout his campaign also softened his stance on various issues after receiving negative feedback.

This comes as analysts pronounced the TPPA dead with Trump's victory.

The reality is, Mustapha said, the US has always thrived on its open culture, which is emphasised perhaps by the number of immigrants serving in its administration, media, universities and scientific institutions, and he believed that a new president won't change that.

In any case Mustapha said that Barack Obama is still president until Jan 20 and we should not be hasty to make any analysis and should take things calmly.

"I am confident that the world will go on. The US is still a powerful economy. It is an important country and an open one, and as the US is the country that will benefit the most from TPPA, it is too early to say," said the minister.

He noted that in terms of trade and investment the US remains our biggest partner.

Asked what would happen if the TPPA is indeed scuttled, he again said that it is still too early to even think of that and it will require consultations with all member countries before any decision is made.

Though he conceded that if the trade deal is dismantled, Malaysia may feel some economic impact, he said that Malaysia will not go back on its commitments with other member countries and will continue to pursue open trade.

Trump won in an upset victory against Hillary Clinton. Even as his supporters celebrate, many around the world wonder if his insular stance may lead to a change in US policy, including the dismantlement of the TPPA he publicly expressed disagreement with.
