"The idea of accelerated membership has been floated in the [European] Commission. This will not happen," Sikorski told the RMF FM radio station.
Poland insists that Ukraine fulfill all the conditions necessary for EU membership, the minister said.
"We believe that Ukraine must fulfill all the conditions, just as we have fulfilled them," Sikorski said.
Achieving candidate status and starting negotiations does not guarantee EU membership. Turkey has been a candidate since 1999, North Macedonia since 2005, Montenegro since 2010, and Serbia since 2012. Croatia, the latest country to join the EU, did so in 2013 after a decade of negotiations.
