In order to ensure that the chemicals it exports will not be used for chemical weapons, the Chinese Government has formulated extremely stringent measures to control its chemical export. As to the two chemicals referred to by the U.S. side, the Chinese Government has clear-cut orders against their export to certain regions. The Chinese Government will, as always, strictly observe its international obligations and make its contribution to safeguarding international peace and security and promoting normal economic and trade exchanges among countries."

COSCO has demanded a compensation of $12.93 million for lost revenues and damage to the company's reputation. State Department Spokesperson Martin Judge rejected the claims and added, "The cargo inspection was done with full consent of China. The U.S. government informed China prior to the commencement of the search that it could not accept any financial liability as a condition of the search."
