Ukraine's EU Membership Negotiations Begin in Earnest: The Future of the "European War" and International Order Also a Question for Japan

The European Union has officially commenced membership negotiations with Ukraine. On June 15, during a meeting in Luxembourg, the EU and Ukraine entered discussions on the "First Cluster," the initial critical area of the membership talks. This cluster covers areas fundamental to state governance, such as the judicial system, fundamental human rights, freedom and security, public procurement, statistics, and financial management.

The German economic news site BUSINESS-PANORAMA.de reported this development as a "historic day," quoting statements from the EU side. Despite the Russian invasion, Ukraine has been pursuing reforms towards the long-term goal of EU membership. The start of these negotiations signifies that Ukraine's efforts have finally progressed to the next institutional stage.

However, it should be noted that the "start of negotiations" and "decision on membership" are entirely different matters. For EU membership, candidate countries must align their national systems with the EU's legal framework and standards. Moreover, political consensus among member states is required to both start and conclude negotiations in each area. In other words, this news marks not the finish line but rather the starting point of a long and arduous marathon.

The significance of starting with the "fundamental" areas is substantial. For the EU, membership is not merely about market expansion. The ability to share values such as democracy, the rule of law, minority rights, transparent administration, and corruption-free public procurement determines a country's eligibility for membership. For Ukraine, under wartime conditions, this is a reform race to bring national systems closer to European standards, alongside military resistance.

Ukraine has warmly welcomed this step. Amid the prolonged Russian invasion, EU membership is not just an economic policy but a security choice that ties the country's future to European political and legal systems. For Ukraine, EU membership signifies not only access to reconstruction funds and markets but also embedding the national will that "Ukraine is part of Europe, not the Russian sphere" into international institutions.

On the EU side, there are calculations as well. Drawing Ukraine into the European framework sends a political message to Russia. Simultaneously, there is an aim to stabilize the Eastern European region, including Moldova. The EU's expansion has historically reshaped the post-Cold War European order by incorporating Central and Eastern European countries. The current negotiations with Ukraine are a continuation of this, but they carry a different weight due to the potential future inclusion of a large nation at war.

Reactions on social media were sharply divided. On X, EU leaders, European Commission officials, and Ukrainian government officials welcomed the development with expressions like "significant progress" and "historic milestone." The EU Delegation to Japan also shared the news in Japanese, highlighting that the negotiations with Ukraine and Moldova begin with the "fundamental" areas related to the EU's core values, thus sharing the news with Japanese-speaking users.

Prominent among the welcoming reactions is the narrative that "since Ukraine is already defending Europe, it should be treated as a member of Europe institutionally." This perspective views Ukraine, which has been resisting Russian aggression, as the frontline of European security. Particularly among supporters from the Baltic and Eastern European countries, there is an argument that delaying Ukraine's membership only gives Russia more time.

On the other hand, cautious opinions remain strong. On social media, questions such as "Membership takes time," "Will anti-corruption measures and judicial reforms truly progress?" and "Can the EU's agricultural policies and budget withstand this?" have been posted. Ukraine is a large country in terms of both population and land, and it is also an agricultural powerhouse. If it joins the EU in the future, it could significantly impact existing member states in areas like agricultural subsidies, regional development funds, single market competition, and labor mobility. It's not an issue that can be resolved with just a welcoming mood.

In international political communities like Reddit, similar mixes of expectations and realism are observed. While there are opinions that Ukraine should be welcomed into Europe, there is also a view that rushing the membership process could lead to institutional fatigue within the EU. Particularly, given Hungary's past obstruction of negotiation progress, there is a growing debate about whether the EU's unanimity rule itself should be reconsidered.

From a Japanese perspective, the first point of attention is the issue of international order concerning the "rule of law." The Japanese government has condemned Russia's invasion of Ukraine as a unilateral change of the status quo by force. This is not just a European issue but one that directly connects to the security environment in East Asia. If changes to borders by military force are tolerated, the same logic could spread to the Indo-Pacific. This is why Japan has been involved in sanctions against Russia and support for Ukraine as a member of the G7.

Secondly, there is the perspective of reconstruction business opportunities for Japanese companies. Ukraine's reconstruction involves diverse fields such as energy, infrastructure, housing, healthcare, communications, agriculture, demining, and urban rebuilding. Japan has already been accumulating support in humanitarian, financial, food, and reconstruction areas, and the Ministry of Economy, Trade, and Industry is advancing collaborative support with European companies and Central and Eastern European countries for Ukraine's reconstruction. As Ukraine aligns more closely with EU standards, there is a possibility that the transparency of legal systems and public procurement will improve, creating an environment where Japanese companies can more easily enter the market.

However, there are risks involved. As long as the war continues, issues such as business continuity risk, insurance, logistics, power supply, securing human resources, and safety management cannot be avoided. Additionally, the demand for transparency in public procurement during EU membership negotiations presents both an opportunity and a potential for intensified competition for Japanese companies. With European, Turkish, American, and Korean companies also targeting the reconstruction market, Japanese companies will need to demonstrate their strengths in specific areas.

Thirdly, this news reiterates the reality for Japanese diplomacy that "Europe and the Indo-Pacific are not separate." Russia's invasion of Ukraine has impacted the entire world through energy prices, food prices, military technology, cyberattacks, disinformation, and sanction evasion networks. For Japan, supporting Ukraine is not just humanitarian aid but also an investment in maintaining international order.

Particularly important is that Ukraine's EU membership negotiations proceed in tandem with "institutional reforms as a democratic state." When continuing to support a country at war, whether the support funds are used appropriately, corruption is curbed, and the judiciary is independent significantly affects public opinion in the supporting countries. In Japan, while there are voices recognizing the necessity of supporting Ukraine, questions such as "How long will the support continue?" and "What will Japan's financial burden be?" exist. Therefore, the strict scrutiny of anti-corruption measures and financial management in EU membership negotiations is a welcome aspect for Japan as well.

Conversely, from a Japanese perspective, maintaining a calm distance is also necessary. Ukraine's EU membership is not something Japan can directly decide. It involves the complex interplay of domestic politics, agricultural policies, financial burdens, immigration and labor policies, and diplomacy with Russia in each EU member state. What Japan can do is respect the EU's process while advancing support and collaboration that leverage its strengths in Ukraine's institutional reforms and reconstruction.

The start of these negotiations also sends a strong political message to Russia. Russia's aim to cut off Ukraine's path to European integration by militarily subjugating it is, at least diplomatically, working in the opposite direction. The invasion has strengthened Ukrainian society's European orientation, and the EU has once again begun to view expansion as a strategic issue for security reasons.

However, it cannot be discussed with optimism alone. EU membership typically takes many years. Ukraine must advance reforms under wartime conditions, addressing numerous challenges such as political stability, financial management, judicial independence, minority rights, media freedom, and administrative capacity. Furthermore, the EU itself will be forced to undertake institutional reforms to accommodate new member states. As the number of member states increases, decision-making on unanimity rules, budget allocation, agricultural subsidies, regional policies, and foreign and security policies will become even more difficult.

The cautious voices on social media reflect this reality. While showing solidarity with Ukraine, there are many voices saying that "membership should be judged by institutions, not emotions." This is not so much a cold opinion as it is a sense of caution to maintain the EU as an institution in the long term. If rushing to welcome Ukraine deepens internal conflicts within the EU, it could actually be advantageous for Russia.

There is much for Japan to learn from this as well. Firstly, collaboration with countries that share values must be established during peacetime, or it will not function during crises. Secondly, reconstruction support must be a comprehensive effort that includes not only infrastructure but also legal systems, administration, transparency, and human resource development. Thirdly, public opinion on social media can become either a tailwind or a headwind for diplomacy, so governments and companies cannot ignore changes in international opinion.

Ukraine's EU membership negotiations could last for several years, possibly even over a decade. However, the start of negotiations on June 15 is a significant milestone in that it demonstrates Ukraine's determination to endure the war while continuing to envision its future as a "member of Europe." From Japan's perspective, this is not merely a negotiation on a distant continent but a matter that connects to its own security, concerning how to support an international order that does not tolerate changes to the status quo by force.

As Ukraine moves closer to the EU, European security and Japan's diplomacy and economy become more closely linked. What role will Japanese companies play in the reconstruction field? How will Japan engage in institutional support that upholds the rule of law? How will the balance between sanctions against Russia and support fatigue be managed? This news prompts Japan to consider these answers as well.

Ukraine's EU membership is not yet a promised future. However, the door to negotiations has certainly opened. Beyond that door, the next phase of the international order, including not only Ukraine but also Europe, Russia, and Japan, is beginning to emerge.
