The European Union has put on hold the visit by Ukrainian President Viktor Yanukovych, EU spokeswoman Maja Kocijancic said on Tuesday.
Yanukovych was due to arrive in Brussels to meet with European Commission head Jose Manuel Barroso and EU Council chief Herman Van Rompuy on Thursday to discuss outstanding details of an association agreement.
Kocijancic said the visit was not cancelled but put off to a later date.
The meeting was postponed "until a later occasion when conditions would be more conducive to make progress on bilateral relations," Kocijancic said.
Ukraine's Foreign Ministry confirmed the postponement.
Ministry spokesman Oleksandr Dikusarov said that Ukraine was interested in resuming dialog with the EU "in the very near future."
The cancellation comes a week after Yanukovych's political rival Yulia Tymoshenko was handed down a seven-year prison sentence on charges of abuse of office.
The verdict has drawn worldwide condemnation.
The EU and the United States have described the trial as politically motivated, and Moscow said it had a "clear anti-Russian subtext."
The EU move comes despite Yanukovych's remarks last Thursday that Tymoshenko's sentence might be commuted.
