The article examines the correlation between international and national legal means of protecting foreign investments through an analysis of the structural design of mechanisms ensuring the guarantees of rights and legitimate interests of foreign investors. It summarizes doctrinal approaches, relevant to the Russian legal scholarship, to understanding the legal regulation mechanism as applied to cross-border investment relations and identifies the key levels of safeguarding guarantees, including normative, procedural, and institutional dimensions. The study outlines national avenues of protection and their linkage with treaty-based international standards, emphasizing the role of jurisdictional and quasi-judicial dispute settlement formats in the practical enforceability of investment guarantees. Particular attention is given to aligning international obligations with constitutional foundations of the domestic legal order and to the significance of auxiliary regulatory instruments shaping consistent law enforcement and predictability of the investment regime. It concludes that the effectiveness of foreign investment protection depends on the coherence between substantive guarantees and the procedures for their implementation, as well as on the stability of interaction between national and international mechanisms within the permissible bounds of State sovereignty.
