In a major concession to the Democrats, the Trump administration has agreed to postpone some protections for an advanced and highly expensive class of drugs called biologics. The final agreement repeals a provision that provided drugs with 10 years of protection against lower-cost alternatives in Canada and Mexico. You`ve almost certainly heard of NAFTA lately. With President Trump`s threats to renegotiate trade deals with countries like Mexico and China, NAFTA has become a controversial issue. But what is NAFTA, why was it created, and how did the world`s largest trade deal to date work? The previous free trade agreement between Canada and the United States had been controversial and divisive in Canada and had been presented as an issue in the 1988 Canadian election. In this election, more Canadians voted for anti-free trade parties (the Liberals and the New Democrats), but the division of votes between the two parties meant that the pro-free trade Progressive Conservatives (P.C.) with the largest number of seats emerged from the election and thus took power. Mulroney and the Progressive Conservatives had a parliamentary majority and easily passed the FTA and Cancan-U.S. NAFTA laws of 1987, but Mulroney was replaced as Conservative leader and prime minister by Kim Campbell. Campbell led the Progressive Conservative Party in the 1993 election, where it was decimated by Jean Chrétien`s Liberal Party, which campaigned on a promise to renegotiate or repeal NAFTA. Chrétien then negotiated two additional agreements with Bush, who had undermined LAC`s consultation process and had worked to "accelerate" the signing before the end of his term, time was up and had to hand over the necessary ratification and signature of the implementing legislation to the new President Bill Clinton.  The momentum for a North American free trade area began with U.S.
President Ronald Reagan, who made the idea part of his campaign when he announced his candidacy for president in November 1979.  Canada and the United States signed the Canada-U.S. Free Trade Agreement in 1988, and shortly thereafter, Mexican President Carlos Salinas de Gortari decided to address U.S. President George H. W. Bush proposed a similar agreement to make foreign investments after the Latin American debt crisis.  When the two leaders began negotiations, the Canadian government of Prime Minister Brian Mulroney was concerned that the benefits That Canada had derived from the Canada-U.S. Free Trade Agreement would be undermined by a bilateral agreement between the United States and Mexico, and asked to become a party to the U.S.-Mexico talks.
