Venezuela turns to Asia as sanctions cut oil flow to U.S., EuropeHOUSTON/MEXICO CITY/MOSCOW(Reuters) - Venezuela's oil exports have tapered off and shifted toward Asia since new U.S. sanctions began Jan. 28 as state-run oil company PDVSA seeks to replace deliveries to the United States and Europe that were disrupted by payment restrictions. The South American nation is turning its focus to cash-paying buyers in Asia and to double its sales primarily in India, its second largest customer after the United States, amid U.S. sanctions designed to undercut financial support for Venezuelan President Nicolas Maduro.
