 According to Vale, the discussions about allowing the "Valemax" ships to enter Chinese ports had been ongoing since the ban came into force and the Chinese officials had given a preliminary go-ahead for the construction of new berths capable of accommodating the 400,000-ton ships.According to the Ningbo Port Company, the construction of the new port facilities would take two to three years, causing further delays for Vale which in the meantime is losing $2–3 per ton of ore due to the ban.On 15 April 2013, "Vale Malaysia" became the first 400,000-ton "Valemax" vessel to call a Chinese port.
