On August 23, Kazakhstan will elect the first members of its new Kurultai, a 145-seat unicameral legislature established under the constitution that entered into force in July. Seven political parties are contesting the election in a single nationwide constituency. All seats will be filled through proportional representation, with no directly appointed deputies. A consequential question is what the newly elected institution will be expected to do.

The distribution of seats and the composition of the new legislature will naturally dominate domestic attention. But the election also has implications beyond Kazakhstan. It will test whether the country can support its increasingly active regional and international diplomacy with an institution capable of translating agreements into legislation, allocating resources over several years, and overseeing their implementation.

This matters because Central Asia’s position in international politics is changing. The region is no longer viewed solely as a space in which larger powers compete for influence. Central Asian states are developing their own positions on connectivity, trade, energy, water management, critical minerals and digital development. They are also engaging collectively with China, the European Union, the United States, the Gulf states and other partners through a growing number of regional formats.

Kazakhstan has been particularly active in this process. Its pragmatic and multivector foreign policy, economic weight and geographic position have enabled it to act as both a regional convenor and a bridge between major markets. Yet geopolitical agency cannot be sustained through presidential diplomacy and international summits alone. It also requires domestic institutions capable of providing legal continuity, budgetary support and public accountability.

Connectivity offers the clearest example. Kazakhstan has become central to efforts to expand the Trans-Caspian International Transport Route, commonly known as the Middle Corridor. But transforming the corridor into a commercially competitive route requires more than diplomatic declarations. It depends on investment in railways, ports, logistics hubs and border infrastructure, as well as reforms to customs procedures, tariffs, digital documentation and public-private partnerships.

Many of these measures require legislation or long-term public expenditure. A parliament able to scrutinize infrastructure priorities, assess financing arrangements and monitor implementation can help turn regional connectivity from a collection of projects into a durable economic strategy. It can also provide greater continuity when individual ministers, officials or government programs change.

The same principle applies to trade and investment. Kazakhstan is seeking to diversify its economy while attracting capital into manufacturing, agriculture, transport, digital services and value-added processing. International investors generally look beyond headline agreements. They examine the stability of tax rules, the enforcement of contracts, customs administration, regulatory transparency and whether commitments will survive political cycles.

The new Kurultai will not determine the investment climate on its own. Nevertheless, its legislative and oversight functions can influence whether economic agreements produce predictable domestic rules. Parliamentary examination of budgets, taxation and sectoral legislation can also help identify gaps between international commitments and their implementation. This is particularly important for large infrastructure and industrial investments whose time horizons extend far beyond a single government program.

Energy and critical minerals present another area where domestic capacity and foreign policy increasingly intersect. Kazakhstan remains an important supplier of oil and uranium, while also seeking investment in renewable energy, electricity infrastructure, mineral processing and the production of materials required for the global energy transition.

International partnerships in these areas raise complex questions about environmental standards, infrastructure financing and the division of risks between the state and private investors. A more coherent legislative system could support a stable regulatory framework while ensuring that agreements contribute to economic diversification rather than simply expanding the export of unprocessed resources.

Water cooperation may offer the most difficult test. Central Asia’s major river systems cross national borders, while climate change, population growth and aging irrigation infrastructure are increasing pressure on available supplies. Regional agreements are essential, but their effectiveness depends on national decisions concerning agriculture, reservoirs, water pricing, infrastructure and environmental protection.

Parliamentary involvement can help connect regional negotiations with the domestic sectors and communities affected by them. It can also provide continuity for investments in water-saving technology and infrastructure that may require sustained funding over many years. In this sense, stronger domestic institutions are not an alternative to regional diplomacy; they are one of the conditions for making it effective.

The move from a bicameral parliament to the Kurultai is intended to create clearer political responsibility and a more streamlined legislative process. Having one chamber may reduce institutional overlap and make it easier for voters to identify which parties are responsible for legislative decisions. With all deputies elected through national party lists, the system may also encourage parties to develop programs addressing countrywide economic and social priorities.

The reforms may also give Kazakhstan’s foreign policy a broader domestic constituency. Its multivector approach has traditionally been guided primarily through presidential and professional diplomacy. A fully elected legislature creates another arena in which the principles underlying that approach, such as sovereignty, strategic autonomy, economic openness and cooperation with competing partners, can be articulated and debated. This matters in an environment where relations with Russia, China, the European Union and the United States intersect with supply-chain security and technological standards. Greater parliamentary involvement can make Kazakhstan’s international positioning more understandable at home and more resilient abroad, demonstrating that it rests on functioning institutions rather than executive preference alone.

The Kurultai can also strengthen parliamentary diplomacy. Relations between countries are shaped not only by governments and foreign ministries, but also through direct engagement between legislators, parliamentary friendship groups and interparliamentary organisations. Foreign lawmakers frequently influence decisions concerning trade preferences, export controls, investment financing, mobility arrangements and international agreements. Sustained engagement with them would provide Kazakhstan with an additional channel through which to explain its policies, address misunderstandings and develop constituencies supportive of cooperation. The foreign-policy benefit of the reform is therefore a broader institutional foundation for its established approach. This could reinforce the country’s reputation as a reliable middle power and make its international partnerships more resistant to political turnover and geopolitical shocks.

The election also includes mechanisms intended to broaden representation. Women, young people and persons with disabilities together account for more than two-fifths of registered candidates, while parties must meet a collective 30 percent quota for these groups both on their lists and when allocating mandates. Greater diversity cannot by itself guarantee legislative effectiveness, but it can widen the range of experience brought into debates over social policy, regional development and economic modernization.

Institutional design, however, does not automatically produce institutional capacity. The effectiveness of the Kurultai will depend on the quality of its committees, the policy expertise of its deputies, the ability of parties to develop distinguishable positions, and the seriousness with which oversight powers are exercised. A more efficient legislative process will be valuable only if efficiency is accompanied by substantive scrutiny. The significance of the election lies in the opportunity to establish a legislature with clearer responsibilities within Kazakhstan’s constitutional system.

The wider regional lesson is that Central Asia’s growing international agency needs to be matched by domestic institutions capable of implementing what governments negotiate abroad.

For that reason, the most important questions after the election will extend beyond which parties win seats. Attention should also be paid to how the Kurultai organizes its committees, uses its budgetary authority, oversees major projects and develops expertise on regional issues.

The election will provide an early indication of whether Kazakhstan can connect ambitious diplomacy with coherent legislative implementation. As the region seeks a larger role in Eurasian affairs, that connection will determine whether regional initiatives remain political declarations or become lasting institutions and infrastructure.
