VASSOURAS, Brazil (Reuters) -Coffee growers in Vassouras, in Brazil's Rio de Janeiro state, are hoping for an eleventh-hour reprieve before the country is subject to tariffs of 50% on its exports to the United States.

Foreign ministry says Beijing has interest in growing Brazil ties, including ‘cooperation on aviation’, with US duties to start on Friday.

Chemical products companies in Brazil, which exported $2.4 billion to the U.S. last year, face a slew of contract cancellations as President Donald Trump has threatened a new 50% tariff on the South American nation's exports from August 1.
