Before that happened, on January 23, 2017, President Donald Trump signed an executive order to withdraw the United States from the agreement. According to analyst and economist B.R. Williams, the United States has played an important role in removing trade barriers and increasing U.S. investment. Williams says the U.S. wants to create a “broader platform for trade liberalization, particularly across the Asia-Pacific region.”  Scholars C. Li and J. Whalley explore a numerical approach to explaining the liberal effects of the TPP. Li and Whalley use a quantitative balance simulation to study the impact of the TPP on trade liberalization and new markets.  In 2014, linguist and political activist Noam Chomsky warned that the TPP “was designed to advance the neoliberal project of maximizing profit and supremacy and putting workers around the world in competition, in order to reduce wages, increase uncertainty.”  Senator Bernie Sanders (I-VT) argues that trade agreements such as the TPP “have destroyed families who end up working and enriched big business.”  Professor Robert Reich asserts that the TPP is a “Trojan horse in a global race to the bottom.”    In October 2018, Japanese Prime Minister Shinzo Abe said that despite its geographical distance, the UK would be welcomed “with open arms” in the CPTPP, indicating that CPTPP member states could use the agreement as a global diplomatic framework in the coming years. The TPP could give new impetus to trade negotiations between China, Japan and Korea and increase the likelihood of a comprehensive regional economic partnership (RCEP) that could provide a possible path to a free trade area in the Asia-Pacific region.  The text of the TPP consisted of thirty chapters including tariffs on goods and services, intellectual property rights (IP), e-commerce rules, environmental and labour standards, dispute resolution mechanisms and many other aspects of world trade.
The goal of this ambitious mega-regional agreement – which spans several continents and covers about 40% of world trade – was to create a fully integrated economic space and to define uniform rules for global investment. For Obama, the pact was a way to ensure that “the United States – not countries like China – are the ones who write the rules of the global economy of this century.” Many pro-TPP economists have recognized that extensive trade, while a net positive for growth, has drawbacks.
