MEXICO CITY, May 12 (Reuters) - Mexico has exported

several cargoes of diesel reprocessed in its new Olmeca refinery

in the port of Dos Bocas, the head of the international trading

arm of state energy company Pemex said on Monday.

Reuters reported in April that two tankers with ultra-low

sulfur diesel, originally produced from crude oil in the Madero

refinery but reprocessed in the Olmeca refinery, had been

exported because of a lack of infrastructure.
