of the U.S, and his claims that he would construct a border wall and force Mexico to fund its construction, caused a decline in the relations of the two countries in the late 2010s. A 2017 survey conducted by the Pew Research Center showed 65% of Mexicans had a negative view of the US, with only 30% having a positive view. This constituted a significant and abrupt drop from 2015, prior to the 2016 United States presidential election, when 67% of Mexicans had a positive view of the United States. The same study also showed only 5% of Mexicans had confidence in the then US leader, President Donald Trump, with 93% having no confidence in him. Similarly, a poll by YouGov showed that less than one in four Americans have a positive image of Mexico. Donald Trump won the 2016 U.S. presidential election partly with campaign promises of building a border wall with Mexico (the 'Trump Wall'). After Trump signed an executive order in January 2017, mandating construction of the wall, Mexican President Enrique Peña Nieto cancelled a scheduled visit to the U.S. Trump said that Mexico would pay for the construction of the wall, but did not explain how; Mexico has in turn rejected the idea of any Mexican funding. Peña Nieto listed ten goals he would seek in NAFTA negotiations, notably safeguarding the free flow of remittances, which amount to about $25 billion per year. In August 2018, Mexico and the United States reached a bilateral agreement on a revamped NAFTA trade deal, including provisions to boost automobile production in the U.S. On December 1, 2018, Mexico inaugurated President Andrés Manuel López Obrador (known as AMLO) as president. In June 2019, a promise of a stricter Mexican asylum program and security tightening to slow the traffic of illegal immigrants into the US averted a possible tariff war between the two countries. The US had threatened a 5% import tariff on all Mexican goods. In April 2020, Mexico closed a plant run by an American company for refusing to sell ventilators to Mexican hospitals during the COVID-19 pandemic. The firm had operated its plant under the argument it provided an “essential” service, when most non-essential plants were closed. Baja California Governor Jaime Bonilla Valdez ordered the factory closed, because it was providing no essential service to Mexicans. He said the company contacted Mexico's Foreign Relations Secretary and the American
