Both the governments of Poland and Hungary share similar nationalist visions that involve keeping out migrants and handing over fewer powers to the European Union.
In Poland, whose government like Hungary's has clashed with Brussels over worries about the rule of law, right-wing Prime Minister Mateusz Morawiecki wished Orban success "for Hungary and for Europe". "The support of the majority of society shows that it's worthwhile to make the effort".
Some other European Union members are likely to view Orban's renewed internal dominance with trepidation, given his repeated run-ins with Brussels institutions over his hardline anti-immigration policies and rejection of the EU's refugee resettlement programme, as well as his moves to clamp down on civil society groups.
"The reason we submitted this package before the elections is in order to allow the Hungarian voters to cast their vote knowing our intention on this", said Orban, 54.
Right-wing Prime Minister Viktor Orban secured a third straight term in the election, with his Fidesz party winning nearly half the vote, likely giving it a two-thirds majority in parliament.
Among the stipulations of the new law, refugee advocates would need government permission for their activities and would pay a tax on their donations from overseas. Orban avoided public debates with opponents or speaking to independent media, preferring instead to address supporters at carefully stage-managed events where he hammered home his anti-immigration message.
German Chancellor Angela Merkel congratulated Orban, pledging that her country will be a "reliable partner" for Budapest, despite differences, her spokesman said.
It is noted that the political bloc of the party of Viktor Orban and the Christian democratic people's party won a constitutional majority.
Orban won re-election after campaigning on a platform that openly demonized migrants to Europe.
Luxembourg's foreign minister, Jean Asselborn, was less enthusiastic: he told Die Welt radio that it was now up to France and Germany to move in and stop the spread of ultra-nationalist populism that Orban represents.
But he added: "The European Union is a union of democracy and values".
Soon after the election victory, the ruling Fidesz party said it could now push on with legislation to crack down on organizations promoting migrant rights after parliament is formed at the end of April. With nearly all of the results counted from the vote on April 8th, Fidesz appears likely to have won a two-thirds super-majority, with 133 of the chamber's 199 seats-enough to alter the country's constitution all by itself.
