Other countries and regions interested in joining the TPP are Taiwan the Philippines and Colombia from 2010; Thailand from 2012; and IndonesiaBangladesh, and India from 2013. According to law professor Edmund Sim in 2013, many of these countries would have to change their protectionist trade policies to join the TPP.  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.  ECIPE stated in 2014 that the TPP would be „the first „competitor” of economic integration large enough to have a significant negative impact on Europe. In the long term, the negative effects of investment, productivity and competitiveness will result from dynamic effects such as. B investment, productivity and competitiveness.  Pascal Lamy called the TPP „the last of the great old-style trade agreements.” : 2 With the two front-rowers Donald Trump and Hillary Clinton speaking out against the deal, he was considered dead when he arrived. Trump`s victory reinforced that view, and on January 23, 2017, he signed a memo in which he told the U.S. representative to withdraw the U.S. as signatories to the agreement and conduct bilateral negotiations instead. In a 2018 study on general foreign trade, researchers found that a large majority of U.S. adults view foreign trade as beneficial to U.S. growth and not a foreign threat.
 In the international context, Americans are generally among the least likely supporters of the Trans-Pacific Partnership and there is a clear partisan divide between American public opinion to support the trade agreement.  „Of course, we also hope that the various free trade agreements in the Asia-Pacific region will be able to communicate and coordinate and create a benevolent interaction, to play a constructive role in their respective fields in resisting trade protectionism and building an open global economy.” The TPP economies accounted for about 40% of the world`s gross domestic product (GDP) and the agreement would have been the largest ever concluded by the United States, both in terms of the number of countries and total trade flows. Data from the U.S. International Trade Commission [PDF] show that in 2015, trade with TPP countries exceeded $1.5 trillion, or about 40 percent of total U.S. trade. The United States has existing free trade agreements with many TPP countries, including Australia, Canada and Mexico, but at the time of the signing of the TPP, an agreement was missing with Japan, the world`s third largest economy. In 2019, the Trump administration negotiated a limited bilateral trade agreement with Tokyo, which, according to U.S. Trade Representative Robert Lighthizer, covers most of the TPP`s economic benefits to the United States.
The EU threat and Trump`s announcement on tariffs are expected to increase the risk of a trade war in which nations are trying to punish each other by raising taxes on goods traded.
