Turkish Foreign Minister Mevlut Cavusolgu on Saturday threatened to impose sanctions on the Netherlands if the country prevented him from entering the country for a campaign rally in Rotterdam in support of constitutional reform.
"If Holland cancels my flight clearance ... we could impose very heavy economic and political sanctions against Holland," Cavusoglu was quoted as telling Turkish broadcaster CNN Turk from Ankara.
Cavusoglu, a member of President Recep Tayyip Erdogan's ruling Justice and Development Party (AKP), is pushing ahead with plans to address fellow Turks at his country's consulate in Rotterdam.
A constitutional referendum in his country, scheduled for April 16, would significantly expand the powers of Erdogan, who has been conducting a widespread purge of government critics since a failed military coup in July.
Dutch Prime Minister Mark Rutte said that, although his government did not want Turkish ministers to campaign in the Netherlands, it did not have the power to cancel events taking place at the consulates of other countries.
"That is Turkish soil - the territory of the Turkish government, but we will be strict about public order and safety" at the event," Rutte told Dutch broadcaster NOS late Friday.
Turkey is at odds with several European countries about its efforts to promote constitutional reform among members of the large Turkish diaspora community.
Cavusoglu held crisis talks with his German counterpart, Sigmar Gabriel, this week in an effort to mend relations after a series of bans on campaign rallies prompted a diplomatic row.
