The cruise industry has become one of the fastest-growing segments of global tourism industry in recent years. Its growth has led to some concerns about its impact on the marine environment, as cruise ships cause no less pollution than regular ships. China’s cruise industry began late but has achieved fast development. However, there are still many challenges related to China’s environmental legislation, and there is no clear-cut legal framework for the environmental protection of cruise ships in the various regulations in China. The legal literature on this issue is insufficient, and this paper attempts to fill the gap. First, it provides an overview of the global cruise industry, including the basic situation of cruise pollution. Second, it briefly introduces the relevant international conventions, and Chinese laws and regulations. Third, it analyzes the recent environmental challenges that cruise ships have faced. The goal of this paper is to give a legal direction for how the cruise industry can grow in ways that are both sustainable and responsible.

Technological innovation is changing the way maritime transport is done, and automated driving is one of the hot topics, including unmanned ships that use automated driving technology, but legal challenges to the application of unmanned ships in the shipping industry must be resolved before that happens—whether and how the principles of existing international conventions regarding unmanned ships. To deal with this problem, it is far from enough to rely on the efforts of international organizations or the revision of international conventions. The paper analyzes several typical legal issues faced by unmanned ships: the legal definition of unmanned ships, the seaworthiness of unmanned ships, the master and crew rules, and the collision and rescue of unmanned ships, taking China as an example, the paper explains reasonable and effective legal path of domestic and international laws, trying to seek solutions at the level of domestic law beyond international convention. The paper concludes that the traditional navigation rules have largely been developed to meet the needs of manned transportation, and cannot be fully applied to unmanned ships. Therefore, until there is an international regulation specifically for unmanned ships, it would be appropriate to interpret or revise existing international conventions to apply to unmanned ships. And for countries including China, it is important to consider the improvement of domestic laws.

The unexpected outbreak of the COVID-19 pandemic has harmed the shipping industry, especially the cruise sector. During this period, the cruise crew, as a neglected subject, experienced great work, life and psychological pressures. However, many states, including China, do not pay enough attention to the legal protection of their rights. The legal literature on this issue is insufficient, and this paper attempts to fill the gap. This paper aims to give a legal suggestion for how to protect the legal rights of cruise crews in ways that are both responsible and effective in the post-COVID-19 pandemic era. To achieve the goal, this paper adopts legal research methods to analyze the application of international conventions and Chinese laws and regulations. The paper discusses the legal limitations on the rights’ protection of cruise crews in the context of the COVID-19 pandemic, and the research results are legal considerations and suggestions for the protection of the cruise crew. In addition to taking reasonable measures to reduce the impact of the epidemic on cruise crews, the legitimate rights and interests of all cruise crew individuals should be realized as much as possible under existing international conventions and domestic laws. It is important for states to further improve crew and labour legislation and strengthen international cooperation to deal with the impact of the global pandemics on the cruise.
