I think you mentioned labour rights. I think the TPP would be a great venue to push forward issues about labour rights, issues about human rights where appropriate, and issues of legal reform. It's hard to do business with a country where the legal system is so corrupt and so convoluted, and up for interpretation in whichever way the government wants.
I think legal reform, labour rights, and human rights are the three key areas that would benefit greatly if we can use the TPP as a venue to push these forward.
