Michael Froman, the U.S. trade representative, says if it passes, countries found to be involved in illegal wildlife trafficking could face trade sanctions.
"What we're doing through the Trans-Pacific Partnership is first of all making sure environmental issues are central to the agreement, including things like wildlife trafficking, and then making them fully enforceable just like any other provision of the trade agreement," he says.
The U.S. is also trying to make this part of a trade deal with the European Union.
But Leigh Henry, senior policy adviser for the World Wildlife Fund, says the Asia-Pacific trade deal is key because much of the demand for the endangered wildlife comes from Asian countries negotiating the TPP.
