 Vale also faced opposition from the China Shipowners' Association which claimed that the Brazilian mining company is seeking to control the freight market as it has already done with the iron ore prices.In the past, the Chinese ports were not allowed to increase their capacity to more than 300,000 tons for dry bulk carriers due to safety and environmental concerns.If the 400,000-ton "Valemax" vessels are allowed to Chinese ports, Vale's monopoly on the route may result in losses for other shipping companies operating capesize ore carriers.
