Exclusive - Mexico's top diplomat visits Cuba to seek help on Venezuela crisis

By Gabriel Stargardter MEXICO CITY (Reuters) - Mexico's Foreign Minister is in Havana hoping to get Cuba, one of Venezuela's top allies, to help resolve the tense political situation in the South American nation, a senior Mexican official who was briefed about the trip said. Luis Videgaray has not gone empty-handed, the official and a document seen by Reuters said, and has accepted Havana's request to expand a credit line with Mexico's state-owned Bancomext bank from 30 million to 56 million euros as a gesture of good will. Cuba uses the credit line to pay for key imports. (Editing by Frank Jack Daniel and Bernadette Baum)
