Meanwhile, Minister Al-Naimi met on Sunday at the Mexican Embassy in Madrid with the energy ministers of Mexico and Venezuela, Ernesto Martens and Alvaro Silva. In a joint communiqué, the ministers expressed their concern that the global oil market is showing a growing imbalance between supply and demand. This is a result, they said, of the slowdown in the world economy causing a drop in the demand for oil and stocks to build up rapidly; but it is also due to increased production by non-OPEC producers, and to the slow pace in implementing the latest supply agreement. They agreed that, in order to forestall further imbalances, effective measures are needed in order to bring supply in line with demand. Expressing their commitment to reduce the oversupply that exists, and stressing that full compliance with standing accords is essential to achieving stability, they agreed to pursue their dialogue with all major producers in order to reduce volatility and ensure market stability, for the benefit of both producers and consumers.
