In 1972, the Convention on the Prevention of Marine Pollution by Dumping of Wastes and Other Matter (London Convention) was negotiated. It is a global treaty, for the first time, to regulate dumping of waste at sea worldwide. Following this global endeavor, the Protocol to the London Convention (London Protocol) was later agreed to further modernize the London Convention so as to reinforce the management of dumping of waste at sea. While in East Asia, only China, Japan, the Republic of Korea (South Korea) and the Philippines have acceded to the Convention and its Protocol, other countries do not show their willingness to sign them. Against this background, this article will address the responses of these East Asian states to the implementation of the London Convention, and analyze and assess their relevant laws and regulations with particular reference to China’s practice. In addition, it will focus on new challenges, such as offshore carbon storage, to the London Convention.
