The variation of countries’ industrial policies and political strategies in a multipolar world brings the investor-state dispute settlement (ISDS) regime to a crossroad. Backlash to the inconsistency, non-transparency, partiality and unfairness of the ISDS regime results from the states’ changing interests and policy priorities, including the rising awareness of democracy. In pursuing the benefits of multilateralism, a multilateral investment court can serve as an alternative to the current investment arbitration regime. States need to clarify the scope of consent based on their political economic considerations. Substantial investment protection standards can be different, whereas the principle of proportionality can serve as an approach to the balance between investment protection and states’ policy arrangements. Meanwhile, there should be efforts to align the interpretation and application of key provisions, possibly through interpretation notes and an appellate body that reviews arbitral decisions, to generalise implicit consensus and to broaden collective acceptance of the regime.

The investor-state dispute settlement (ISDS) system is such a means to an end of further economic development and wider social political goals. With major protective provisions of expropriation against compensation, fair and equitable treatment, national treatment, most-favored-nation treatment, full protection and security and umbrella clause, it helps establish a predictable, transparent, and enforceable legal regime to protect foreign investors’ legitimate expectations and lawful investment. As China intends to attract foreign investments by offering a stable business operation environment, its signing a large number of BITs and FTAs may help reduce political and socio-economic risks, which give states, businesses, and individuals the confidence to work in a coordinated manner. The economic development goal, rule of law strategy, tense US-China relations, ideology of multilateralism and community of common destiny, all add up to China’s inclination to incremental but effective ISDS reform.

The calls for reform of investment treaty regime are neither novel nor entirely unexpected. And the need for that reform has recently reached its pitiful nadir where the UNCITRAL Working Group III gathered for its first meeting in Vienna back in November-December 2017 to discuss states’ concerns about investor-state dispute settlement. States’ concerns about the reform have been repeatedly referred to in recent publications, but international scholars have not yet discussed Russia's stance in detail. In the following an attempt has been made to fill the gap in literature by introducing the Russian position which contrasts nicely with Canada or the EU. Why is this important? Russia is a significant state in the UNCITRAL Working Group III and any slight shifts in its approach in the UNCITRAL reforms are closely watched. It is the right time to provide an analytical framework for understanding the Russian position in these reform dynamics.

The 2018 amendment of the KORUS has made an important stride in the investment chapter of the agreement. In particular, the amendment introduced new provisions to regulate multiple, subsequent or parallel ISDS proceedings involving the same governmental measures. The new provisions, however, arguably contain inherent limitations. They will be able to address only some of the multiple, subsequent or parallel proceedings. They then leave open a possibility where essentially the same investor raises a series of ISDS proceedings against essentially the same measures by an advance planning on the scope of ‘measures’ and/or form of ‘control.’ This means that the new provisions will not be able to fully prevent multiple, subsequent or parallel proceedings in the same context or circumstances from taking place, as was originally intended by the drafters. More detailed wordings and elaborations would have helped to achieve the objective. Future Joint Committee discussions or additional amendments should consider such clarification or elaboration.
