Romanian officials have been left red-faced after Germany's foreign minister was handed a brochure with a map of France.

Frank-Walter Steinmeier received the gift from Romanian counterpart Bogdan Aurescu at the end of a news conference Monday to mark 135 years of diplomatic relations.

Romania's Foreign Ministry later apologized saying it had received the brochure in the morning containing the "regrettable technical error" — the colors of the German flag contained within the map of France — from news agency Agerpres.

Aurescu apologized to Steinmeier during a visit later to the city of Sibiu. Steinmeier responded diplomatically, saying he hadn't even noticed the gaffe, the ministry said.

Romania also celebrates 135 years of diplomacy this year with Britain and France.
