Ankara: Turkey’s foreign ministry on Tuesday said the European Union was exercising democratic values selectively and that it should not be standing by the Netherlands, which it accused of violating human rights and European values.

Ankara has suspended high-level diplomatic relations after Dutch authorities prevented its ministers from speaking at rallies of expatriate Turks, worsening a row between the Nato allies.

In a joint statement on Monday, EU’s foreign policy chief Federica Mogherini and enlargement commissioner Johannes Hahn called on Turkey to refrain from “excessive statements” to avoid further escalating the dispute.

“EU counterparts are exercising democratic values and basic rights and freedoms selectively,” the foreign ministry said in a statement. “It is very grave for the EU to hide behind member country solidarity and stand by the Netherlands, which has clearly violated human rights and European values,” it said.

Mogherini and Hahn’s statement included “inaccurate assessments”, the foreign ministry said.

“It should be understood that the EU’s statement ... actually helps the cause of extremes such as xenophobia and anti-Turkish sentiment,” it said.

President Tayyip Erdogan, who is seeking Turkish voters’ support in an April 16 referendum on boosting his powers as head of state, had accused the Dutch government of acting like “Nazi remnants” for barring his ministers.

The sanctions include the banning of the Dutch ambassador and diplomatic flights from the Netherlands. They do not appear to include economic measures or travel restrictions for ordinary citizens.

Dutch Prime Minister Mark Rutte on Tuesday said that the sanctions were “not too bad” but were inappropriate as the Dutch have more to be angry about.

Chancellor Angela Merkel derided as “clearly absurd” Erdogan’s accusation that Germany supports terrorism.

After Erdogan excoriated Merkel’s government for “openly giving support to terrorist organisations” on Monday, the Turkish government announced it would block the Dutch ambassador from re-entering the country. Erdogan has blasted European leaders, including accusing Germany of using “Nazi practices,” after a string of rallies by Turkish ministers on European soil were cancelled.

“The chancellor has no intention of participating in a competition of provocations” with Erdogan, her chief spokesman, Steffen Seibert, said in an emailed statement on Monday. “She’s not going to join in with that. The accusations are clearly absurd.”

Erdogan is seeking votes from Turkish expatriates in a referendum next month on constitutional changes that would make the presidency his country’s highest authority. He has lashed out at the European Union and risked deepening tensions, particularly with Merkel. In an interview on Monday, he said Merkel’s government “mercilessly” supported groups such as the Kurdish PKK group, which has waged a separatist war with the Turkish military for more than three decades.
