Non-Opec oil exporter Yemen posted a 75 per cent drop in oil revenues in the first three months of 2009 as crude prices weakened, according to the country's central bank.

Yemen's oil revenues fell to $365.1 million in the first quarter, compared to $1.46 billion in the year-earlier period, the central bank said in a report.
