Another negotiation round for a Trans-Pacific Partnership (TPP) agreement has recently wrapped up in Ottawa, Canada, without any deal, even on a date for the next meeting.

The reason was attributable to major differences held by the 12 participating State members over contentious issues, including those on intellectual property, State-owned enterprises and environment.

The negotiating countries agreed to continue holding meetings to address their differences but could not decide when their next sitting will be held.

TPP negotiations began in 2010 with the participation of nine nations.

It is now involved by 12 countries, including the US, Australia, Brunei, Canada, Chile, Malaysia, Mexico, New Zealand, Singapore, Peru, Japan and Vietnam.

Once signed, the agreement will create a free trade area with an 800 million population, accounting for 30 percent of total trade turnover and nearly 40 percent of economic output of the globe.-VNA
