Relations between Hungary and Ukraine have deteriorated significantly over the past month. In early March, Hungarian authorities arrested seven Ukrainian bank workers who were transporting millions of US dollars worth of cash and gold through Hungary to Ukraine.
Hungary’s tax authority said they had been detained on suspicion of money laundering, which prompted a furious response from Ukraine. In a post on social media, Ukraine’s foreign minister Andrii Sybiha denounced what he called “state terrorism and racketeering”.
This incident followed an earlier decision by the Hungarian prime minister, Viktor Orbán, to deploy the military to guard power plants after warning that Ukraine planned to disrupt his country’s energy system. Orbán had previously accused Kyiv of holding back Russian oil deliveries through the Druzhba pipeline, which passes through Ukrainian territory.
