HAVANA, May 30 (Xinhua) -- The Cuban government summoned the highest diplomatic representative of the United States in the country, Mike Hammer, to protest his "provocative and irresponsible" behavior, the Cuban Ministry of Foreign Affairs said Friday.

The ministry delivered a note of protest to Hammer, chargé d'affaires of the United States in Havana.

"By inciting Cuban citizens to commit criminal acts of marked gravity, attack the constitutional order or encourage them to act against the authorities, and to demonstrate in support of the interests and objectives of a hostile foreign power, the diplomat assumes a provocative and irresponsible conduct," said the note.

It indicated that the immunity enjoyed by Hammer as a representative of his country cannot be used as cover for acts contrary to the sovereignty and internal order of the country before which he is accredited.

According to the note, the diplomat has violated the Vienna Convention on Diplomatic Relations and also the agreement to re-establish diplomatic relations signed between the two governments.

In recent weeks, Hammer visited several Cuban cities, where he met with opponents of the government. He also announced that the White House will apply new measures to tighten the blockade that the United States has applied to the island for more than six decades in a press conference in the U.S. city of Miami. ■
