The State Secretariat for Economic Affairs (SECO) is a Swiss government agency responsible for coordinating economic policy, promoting trade, and ensuring sustainable economic development. In the context of sanctions and financial crime compliance, SECO plays a vital role in implementing Switzerland's sanctions policies, aligning them with international regulations and obligations. 

SECO oversees the enforcement of economic sanctions against individuals and entities that pose threats to national or international security, such as those involved in terrorism or serious violations of human rights. The agency provides guidance to financial institutions and businesses relating to compliance with these sanctions, ensuring that they conduct proper due diligence and reporting. By fostering a culture of compliance and transparency, SECO helps protect Switzerland’s financial system from illicit activities and reinforces its commitment to maintaining the integrity of its international financial standing.
