Document Introduction

This report is based on a client alert issued by Latham & Watkins LLP on August 18, 2025. It systematically outlines a series of the latest sanctions measures implemented by the European Union and the United Kingdom against Russia and related parties from December 2024 to July 2025. The report focuses on the continuous evolution of the sanctions regime, particularly how it has been closing loopholes, expanding scope, and strengthening enforcement mechanisms through multiple sanctions packages. This reflects the Western alliance's refined and long-term strategy of exerting economic pressure on Russia.

The main body of the report provides a detailed chronological analysis of the core content of the EU's sanctions packages from the 15th to the 18th. Key developments include: a significant expansion of the targets from entities within Russia to third countries and individuals, including those from China, Turkey, and India, demonstrating the trend of secondary and extraterritorial application of sanctions; regarding Russian oil exports, measures have evolved from the initial price cap mechanism to attempts to block backdoor entry into the EU market via refining in third countries, introducing strict crude oil origin certification requirements; in terms of trade restrictions, the embargo list has been continuously expanded, covering various goods from specific industrial software (e.g., for oil and gas exploration, banking), electronic products (e.g., video game controllers), to primary aluminum.

The report pays special attention to the strengthening of sanctions enforcement mechanisms. In the 16th package, the EU extended the 'best efforts' obligation from existing trade sanctions regulations to other areas of Russia sanctions such as asset freezes, requiring EU natural and legal persons to exert influence on non-EU companies under their control to ensure they do not engage in activities undermining EU sanctions. Furthermore, sanctions measures include expanding transaction bans on Russian banks (including de-SWIFTing and targeting banks using Russia's financial messaging system), restrictions on specific ports and infrastructure, and countermeasures against legal tools involved in so-called investor-state disputes.

In addition to EU actions, the report also analyzes the progress of UK sanctions against Russia in 2025. The UK, in coordination with the US, lowered the price cap for seaborne Russian crude oil and followed the EU in banning the provision of specific types of industry software to Russia or persons associated with Russia, while providing limited transitional licenses for the business exit of multinational companies. These measures by the EU and the UK maintain coordination in core areas, collectively forming a complex network of economic pressure on Russia.

The content of this report is strictly based on published official regulations and legal analysis. It aims to provide researchers, policy analysts, and businesses affected by sanctions with an authoritative overview and summary of key recent developments in Western sanctions against Russia. This report does not constitute legal advice but reveals the clear trend of increasing complexity, expansion, and strict enforcement within the current sanctions system. It holds significant reference value for understanding the legal warfare and rule-shaping in great power economic competition.
