World Bank report showing minimal growth in developed countries under TPP expected

A spokeswoman for Trade Minister Andrew Robb told Fairfax Media the agreement would deliver benefits by driving integration across the Asia-Pacific and establish one set of trading rules across 12 countries.

"The World Bank report demonstrates that all 12 member countries -- representing around 40 percent of global GDP -- will experience economic growth and increased exports," the spokeswoman said.

However trade between member and non-members states will be more difficult under the "cumulative rules of origin."

The rules state members will lose trade privileges under the agreement if they source inputs from outside of TPP members states, essentially forming a preferential trade agreement rather than a free trade agreement.

The World Bank's report is the first comprehensive economic analysis on the TPP, which will not come into effect until a majority, or at least 6 of the 12 signatories representing 85 percent of the combined GDP have ratified the treaty.

The analysis shows the TPP will benefit Australia's economy by 0.7 percent by 2030, the United States by 0.4 percent while Vietnam will be boosted by 10 percent and Malaysia by 8 percent.

It is expected the deal will be signed in New Zealand in the beginning of February.
