Twelve Pacific region trade ministers signed the Trans-Pacific Partnership in Auckland, New Zealand, on Thursday - a broad free-trade deal that will cut taxes and trade barriers for nearly half of the world's economy.
Trade Representative Michael Froman signed for the United States.
All the ministers said their goal is to "enhance shared prosperity, create jobs and promote sustainable economic development for all of our nations."
The agreement is considered one of President Barack Obama's proudest achievements in his seven years in office.
Obama issued a statement saying the deal will bolster American leadership abroad and support good jobs at home. He said he will push U.S. lawmakers to quickly ratify the deal.
"I'll continue working with Democrats and Republicans in Congress to enact it into law as soon as possible," he said, "so our economy can immediately start benefiting from the tens of billions of dollars in new export opportunities. We should get TPP done this year and give more American workers the shot at success they deserve and help more American businesses compete and win around the world."
7 years in making
It took seven years of often contentious negotiations to complete the trade deal.
The deal basically reduces tariffs and trade barriers for numerous goods and services, including cars, medicines and dairy products. It also sets rules for labor and environmental protection, and protects intellectual property rights for multinational corporations.
