China's rising refined oil exports are already having an impact and will continue to influence other markets in Asia and in the Far East as the country's capacity increases, experts said.

China's net diesel exports will expand to more than 6 million metric tons next year due to slowing domestic demand and growing output, said Li Li, research director at ICIS C1 Energy, a Shanghai-based energy information consultancy.

She estimated that the country's net diesel exports will reach 3.5 million tons this year.
