Eurostat data shows over 4.3 million Ukrainians remain under temporary protection in the EU, with the mechanism extended to March 2027. A UNHCR report projects that under a 'fragile peace with concessions' scenario, 56% of Ukrainian refugees (2.9 million) will remain in Europe until at least 2029. Under a status quo scenario of continued aggression, 99% would stay; under a Ukrainian victory scenario, the number could drop to 32%. The EU is discussing post-2027 status options.

Ukraine's Minister for Communities and Territories, Oleksii Kuleba, reported that over 50% of businesses in frontline territories are inactive or partially operating, resulting in up to 100,000 job losses. The government has enshrined 'frontline territories' in the state strategy for regional development for the first time, directing at least 50% of the State Fund for Regional Development to projects in these areas. Priorities include rapid repairs of housing and critical infrastructure, development of protective infrastructure, and support for healthcare, education, logistics, agriculture, and business.

Background: On May 15, 2025, Russian President Vladimir Putin signed a decree simplifying Russian citizenship for residents of Moldova's breakaway Transnistria region, exempting them from residency, language, and history requirements. Today: Moldovan President Maia Sandu, during a state visit to Tallinn, Estonia, publicly condemned the decree as a recruitment tool for Russia's war in Ukraine, stating 'probably they need more people to send to the war in Ukraine.' She noted that since the full-scale invasion began, most Transnistrian residents have sought Moldovan passports to avoid forced mobilization. Ukrainian President Volodymyr Zelensky condemned the decree as 'Russia’s way of staking a claim to Transnistria’s territory' and ordered Ukraine's Foreign Ministry to coordinate a response with Moldova. Moldovan Prime Minister Alexandru Munteanu echoed Sandu's concerns, warning that a Russian passport carries obligations and that Moldova may summon the Russian ambassador. Sandu dismissed any Russian influence over Moldova's EU accession, asserting 'only the EU can decide whether Moldova can become part of the EU or not. Russia has nothing to do with this.'

Monocrystal, a leading Russian producer of synthetic sapphires used in missiles and drones, has filed for bankruptcy due to production damage from Ukrainian attacks, supply disruptions, loss of European markets, and falling Asian demand. The company's liabilities exceed assets by $50.6 million, and its workforce has halved since 2022. This development highlights the impact of Western sanctions and Ukrainian strikes on Russia's high-tech defense supply chain.

Russia is recruiting Yemeni fighters to fight in Ukraine, offering upfront payments of $15,000, monthly salaries of $5,000, and Russian citizenship. Many recruits are former combatants from Yemen's civil war, lured by financial incentives amid poverty. Reports indicate some fighters have been killed or disappeared, and families plead for their return. The Yemeni government has not taken public action.

Deputy Minister of Digital Transformation Oleksandr Bornyakov described how drones provide real-time intelligence on Russian positions and enable strikes on oil facilities, while AI has moved from operational to strategic command levels. The United Kingdom will fund an AI center under Ukraine's Defense Ministry to further implement these technologies.

The Institute for the Study of War (ISW) assesses that Russia's senior military command has presented highly inaccurate battlefield assessments for five months, falsely claiming advances west of Kupyansk. Ukrainian forces advanced near Hulyaipole and continued long-range strikes on Russian defense industry in Stavropol Krai. Russia also expanded passportization in Transnistria.
