During a debate in the European Parliament before the Christmas holidays, Mr De Gucht said it that Congo was in a bit of a mess right now with no reliable contact person to deal with regarding aid to the country.
The reaction of the Congolese authorities was to accuse Mr De Gucht of being a racist and to refuse to give him a visa to enter the country.
The Congolese ambassador to the European Union has been chided for this move.
European Commission President José Manuel Barroso said that Karel De Gucht had the full backing of the entire commission and the European Union.
