This article examines the policy background and legislative frameworks underlying the regulation of transboundary movement of potentially invasive alien species (IAS). The starting point is the examination of the fundamental regulatory concepts for IAS that are found in (1) the International Plant Protection Convention (IPPC) (in accordance with the World Trade Organisation’s Agreement on the Application of Sanitary and Phytosanitary Measures, ‘SPS Agreement’) and (2) the Convention on Biological Diversity (CBD), together with a discussion on whether IAS are legally regarded as ‘pests’. How these concepts are applied in different transboundary situations is then examined with examples from within federal jurisdictions (USA, Australia) and across external and internal boundaries in transnational jurisdictions (European Union and Eurasian Economic Union). Special attention is paid to IAS in aquatic environments and the question of naturalisation of once alien species. The article concludes with suggestions for development of future policy on IAS taking into account the degree of effectiveness of present regulatory frameworks and the need to consider the impact of climate change on future threats from invasives.

外来入侵物种跨境流动的生物安全框架

本文探讨了潜在入侵性外来物种 (IAS) 越境转移监管的政策背景和立法框架。起点是检查 IAS 的基本监管概念，这些概念见于 (1) 国际植物保护公约 (IPPC)（根据世界贸易组织的卫生和植物检疫措施应用协议，“SPS 协议”） ) 和 (2) 生物多样性公约 (CBD)，以及关于 IAS 是否在法律上被视为“害虫”的讨论。然后通过联邦管辖范围内（美国、澳大利亚）以及跨越跨国管辖区（欧盟和欧亚经济联盟）的外部和内部边界。特别注意水生环境中的 IAS 和曾经外来物种的归化问题。文章最后提出了制定 IAS 未来政策的建议，同时考虑了当前监管框架的有效性程度以及需要考虑气候变化对未来入侵者威胁的影响。
