Sanctions against the firms involved — some of the largest in Brazil — have limited their business opportunities, producing a ripple effect on associated businesses and contractors but creating opportunities for foreign companies to step into what had been a closed market. The succeeding TEMER administration has implemented a series of fiscal and structural reforms to restore credibility to government finances. Congress approved legislation in December 2016 to cap public spending. Government spending growth had pushed public debt to 73.7% of GDP at the end of 2017, up from over 50% in 2012. The government also boosted infrastructure projects, such as oil and natural gas auctions, in part to raise revenues. Other economic reforms, proposed in 2016, aim to reduce barriers to foreign investment, and to improve labor conditions. Policies to strengthen Brazil’s workforce and industrial sector, such as local content requirements, have boosted employment, but at the expense of investment. Brazil is a member of the Common Market of the South (Mercosur), a trade bloc that includes Argentina, Paraguay and Uruguay - Venezuela’s membership in the organization was suspended In August 2017. After the Asian and Russian financial crises, Mercosur adopted a protectionist stance to guard against exposure to volatile foreign markets and it currently is negotiating Free Trade Agreements with the European Union and Canada.
