Russian Deputy Foreign Minister Sergey Ryabkov said on Tuesday that Moscow remains optimistic about implementing a diesel agreement reached with the United States. He presented the government as ready to move the arrangement forward, although the short statement did not announce a start date for deliveries. The report also left out the quantity of diesel covered, the companies involved, and the destination markets. Those details would determine how quickly the deal could be carried out and how closely the parties would need to coordinate. Ryabkov's comments point to continued Russian interest in completing the transaction, despite uncertainty over when it will take effect. Nothing in the statement said that shipments had already begun or that every outstanding condition had been met.
