The European Commission has proposed up to 15 years of post-accession safeguards to punish new member states in case of bad behaviour, in a long-delayed pre-enlargement policy review out on Tuesday (6 October).

The reforms were initially requested by the European Council in June 2024 to be ready by spring 2025, but were delayed several times due to political sensitivities in EU capitals.

They are aimed at frontrunners for future EU membership – Montenegro, Albania, Moldova, and Ukraine – each of whom will get an accession roadmap this month.

EU Commission president Ursula von der Leyen has deemed union enlargement a “geopolitical imperative” amid the war in Ukraine and shift towards a new global order.

By expanding, the EU hopes to promote democracy and strengthen the single market.

But this also comes with fears that countries could misbehave after getting in, prompting the commission’s proposed new guardrails.

The commission suggests that new member states promise “not to oppose EU decisions on future enlargements” due “to bilateral disputes” for an unspecified time.

But Marta Kos, the EU’s enlargement commissioner, said this commitment would be voluntary.

Commissioner dismisses ‘two-tier’ concerns

Ukraine and Moldova could advance to two further stages of their European Union accession negotiations as early as next week, Enlargement Commissioner Marta Kos has said, provided Ukraine approves legislation addressing minority-language education.

The European Union could open two additional negotiating clusters with Ukraine and Moldova next week if the Ukrainian parliament passes legislation intended to address concerns over education rights for national minorities.

EU Enlargement Commissioner Marta Kos confirmed the possible timetable on Monday following a meeting of the EU-Moldova Association Council in Brussels.

Asked whether further intergovernmental conferences could take place this month, Kos said the next two clusters could potentially be opened during meetings in Luxembourg next week.

The condition is passage by the Verkhovna Rada of legislation dealing with educational rights for national minorities, an issue that has been central to Hungary’s objections to further progress in Ukraine’s accession negotiations.

Kos said during the Commission’s recorded press conference that Brussels was aware of the Ukrainian parliament’s procedures and hoped the legislation would be approved. Member states would then have to complete their own procedures quickly.

A draft law covering education rights for indigenous peoples and national minorities was registered in the Verkhovna Rada on 1 October.

The legislation is intended in part to address Hungarian demands concerning the use of minority languages in Ukrainian schools, particularly by the ethnic Hungarian community in Zakarpattia.

Hungary has repeatedly linked support for Ukraine’s EU accession process to those issues.

Ukraine and Moldova formally opened accession negotiations in 2024 and have since moved into the detailed cluster-based process used to organise negotiations over the EU acquis.

EU Today reported in June that the two countries had moved into the first substantive stage after political agreement allowed negotiations on the “fundamentals” cluster to proceed.

That cluster covers areas including the judiciary, fundamental rights, public administration, democratic institutions, public procurement and financial control.

Unlike most negotiating areas, the fundamentals cluster remains open throughout the accession process and is normally closed last.

The possible opening of two additional clusters would therefore mark another practical step in a process that remains dependent on unanimous support among EU governments at key stages.

Ukraine’s Foreign Minister Andrii Sybiha has said he hopes adoption of the minority-education amendments will remove the remaining basis for Hungary to block the next steps.

The negotiations have also become linked increasingly closely to the wider security relationship between the EU and Ukraine.

EU Today has followed the accession process as Kyiv and Chișinău seek to keep negotiations moving despite political resistance within the bloc.

Brussels continues to stress that accession remains merit-based and conditional on reforms.

Kos said on Monday that both Ukraine and Moldova were delivering reforms in difficult circumstances and described them as being among the four front-running candidate states.

The Commission is due to publish its annual enlargement reports on 28 October, providing a detailed assessment of progress across individual negotiating chapters.

Moldova has set itself a target of being ready to complete negotiations by early 2028, although any final accession date would depend on the member states.

The country has also been moving closer to EU structures outside the formal accession negotiations.

Kallas said on Monday that the EU had committed €1.9 billion under its Growth Plan for Moldova and was releasing another €157 million tranche. Moldova has joined the Single Euro Payments Area and is moving towards inclusion in the EU’s mobile roaming area.

Ukraine’s path is more politically complicated because of both the war and recurring disputes with individual EU members.

The next immediate test is parliamentary: whether Kyiv can pass the education amendments quickly enough to allow EU governments to approve the next negotiating stages in Luxembourg.

EU foreign policy chief Kaja Kallas has warned that Russia is intensifying hybrid operations across Europe, citing sabotage attempts, airspace violations and Russian drones and missiles crossing into Moldovan territory.

Her intervention adds pressure for a more coordinated European response to hostile activity below the threshold of conventional warfare.

Russia is putting lives at risk across Europe through an expanding campaign of hybrid activity, EU foreign policy chief Kaja Kallas said on Monday, after another series of Russian drones and missiles entered Moldovan airspace.

Speaking in Brussels alongside Moldovan Prime Minister Vasile Tofan and Enlargement Commissioner Marta Kos, Kallas said Europe had experienced an increase in sabotage attempts and airspace violations during recent weeks.

“Russian missiles and drones violated Moldovan airspace again over the weekend,” she said, describing the incidents as unacceptable.

According to the official EU record of the press conference, Kallas said the Kremlin was seeking to create fear and interfere with European decision-making, and argued that the response should include greater resilience and continued support for Ukraine.

Her remarks follow Russia’s renewed large-scale attacks against Ukraine’s energy system and continued reports of drones crossing borders beyond Ukrainian territory.

Moldova’s defence authorities reported that three drones entered Moldovan airspace during Russia’s 30 September attack on Ukraine. Moldova, which shares a long border with Ukraine and is seeking EU membership, has repeatedly accused Moscow of attempting to destabilise the country.

The latest incidents broaden a European debate that has been developing for months: how governments should respond to hostile operations that are deliberate and potentially dangerous but fall short of an overt military attack.

EU Today reported on 28 September that European governments were discussing an emergency security protocol intended to improve coordination when member states face sabotage and other hybrid threats.

That followed earlier warnings concerning suspected attacks on infrastructure, cyber operations, interference campaigns and airspace violations across several European countries.

The problem is partly one of attribution and partly one of thresholds.

A conventional armed attack on a NATO member may trigger consultation under Article 4 or, in sufficiently serious circumstances, collective defence provisions under Article 5. The European Union also has its own mutual assistance provision under Article 42.7 of the Treaty on European Union.

Hybrid activity is frequently designed to remain below those thresholds.

Cyberattacks, covert sabotage, GPS interference, disinformation, drones and operations conducted through intermediaries can impose costs without giving governments an obvious basis for a military response.

Kallas’s warning comes as Germany has also reported an increase in activity it attributes to Russia.

Chancellor Friedrich Merz has warned that Germany faces growing hybrid pressure involving drones and cyber operations. European security services have separately investigated suspected Russian involvement in sabotage and attacks on infrastructure in several countries.

Moscow has denied Western accusations that it is directing such operations.

The EU has already used sanctions against individuals and entities accused of Russian hybrid activity, while governments are considering faster systems for sharing intelligence and attributing incidents.

EU Today examined the debate in September as the European Parliament considered proposals for quicker attribution, stronger intelligence-sharing and improved protection of critical infrastructure.

Moldova occupies a particularly exposed position.

The EU has provided €317 million through the European Peace Facility for Moldovan defence modernisation, according to Kallas, including €120 million allocated in 2026 for air defence. Brussels is also supporting Moldova through its EU Partnership Mission, which provides assistance against hybrid and cyber threats.

Unlike Ukraine, Moldova is not a NATO member and has constitutional neutrality. Its ability to counter Russian missiles or drones entering its airspace is therefore closely connected to the development of its own detection and air-defence capabilities.

For the EU, repeated incidents involving Moldova, NATO airspace and European infrastructure are increasingly being considered as parts of the same security problem rather than isolated events.
