More than a dozen top European Union officials are in Kyiv today, a top-level demonstration of support following new pledges of military aid as the first anniversary of Russia's invasion of Ukraine nears.
While the EU backs Ukraine and supports democratic and economic reforms there, Kyiv's hopes to quickly join the 27-nation EU are set to be dashed.
Here is why - and details about EU accession:
Ukrainian Prime Minister Denys Shmyhal has said he wanted Ukraine to join the European Union in two years and a liberal Belgian EU politicians said teasingly he dreamt of it happening over the next five.
In reality, that is most likely to take much longer.
The last country to have joined the EU was Croatia in 2013, a decade after formally applying.
Ukraine's neighbour Poland took 20 years until joining in 2004.
Ukraine applied to join shortly after it was invaded by Russia last year and last June received a formal candidate status from the EU, which cast it as a bold geo-political move.
To be allowed in, Ukraine needs to fulfil extensive criteria from political stability including democratic institutions guaranteeing the respect of the rule of law and human rights to economic ability to withstand more competition.
Ukraine will have to transpose its national law to extensive EU legal standards from climate to labour to health, among others.
While the bloc recognises progress so far, it stresses Ukraine needs to do more to build a credible track-record of fighting endemic corruption.
Beyond that, the EU highlights reforms necessary to ensure that courts are free from political meddling and the rights of minorities respected in Ukraine.
Accession criteria do not specifically say a country at war cannot become an EU member but the bloc does not want to import territorial conflicts.
It did, however, allow Cyprus to join in 2004 despite Nicosia not controlling the whole island since Turkey's 1974 invasion.
Turkey, a NATO ally, has seen its own EU membership negotiations unravel in recent years as President Tayyip Erdogan's crackdown on critics following an attempted coup in 2016 undermined democracy there and soured ties with the bloc.
The negotiations started in 2005 after decades of Turkey seeking a formal start to an EU membership bid, dovetailed with Erdogan's first economic reforms in power as prime minister from 2003 that made Ankara an important emerging market economy and trade partner.
All EU countries must agree to take a new peer in.
Beyond Ukraine meeting the complex criteria, it would also have to overcome reluctance from several founding states including France and the Netherlands to expand the bloc more to the east.
EU enlargement talks have stalled since 2018 as the current members cannot agree whether to admit other official candidates Albania, North Macedonia, Moldova, Montenegro and Serbia.
The bloc is also divided on awarding formal candidate status to other hopefuls Bosnia and Herzegovina, Kosovo and Georgia.
With some 44 million people, Ukraine would be the fifth-biggest EU country after Germany, France, Italy and Spain, giving it large influence on the bloc's decisions.
