Mr Puigdemont, 54, told Belgium television that he wanted to appear “before the true Justice (of Belgium), not before the Spanish”.
He said that wanted to appear before the judges but that did not mean a Spanish court.
Mr Puigdemont said: “I will not run from justice. I will go to the justice authorities, but the real justice authorities.
“I have told my lawyer to tell Belgian justice authorities that I am completely ready to cooperate.”
Mr Puigdemont added it was “very clear that the Spanish justice authorities had become politicised”.
In an interview with the French-language RTBF channel broadcast this evening reaffirmed his stance that he had not “fled” from justice and that he is in Belgium to prepare his defence.
Mr Puigdemont said: “I have not fled, but it is impossible to prepare well.”
Also in the interview he said that he was “willing to be a candidate” in the regional elections on December 21 and added that he could campaign from abroad.
Mr Puigdemont’s lawyer, Paul Bekaert, has already announced that he will “appeal” if a Belgian judge accepts the expected arrest warrant from the National Court judge Carmen Lamela.
Mr Bekaert said that he would “undoubtedly appeal” any court order or extradition warrant in an attempt to avoid being sent to Madrid.
Mr Puigdemont was dismissed by Madrid as Catalan leader after the region’s unilateral declaration of independence, travelled to Belgium and failed to appear in a Spanish court on Thursday to answer charges of rebellion. But nine associates were remanded in custody in Madrid pending possible trial.
Mr Puigdemont’s deputy Oriol Junqueras was jailed yesterday along with seven other ministers as Spain continued its attempt to crush the north-east region’s bid for independence.
Mr Junqueras, along with ministers Jordi Turull, Josep Rull, Foreign Affairs Minister Raül Romeva, Interior Minister Joaquim Forn, Justice Minister Carles Mundó, Dolors Bassa, Meritxell Borràs were all imprisoned in various Madrid jails.
They are all accused of rebellion, sedition and misuse of public funds.
Spanish judge Carmen Lamela said she had ordered eight Catalan leaders, including former rice-president Oriol Junqueras, to be remanded in custody pending an investigation into Catalonia‘s independence push and a potential trial.
Another, Santi Vila, who stepped down from the Catalan cabinet before a unilateral declaration of independence last Friday and has since then been pushing for a negotiated solution with the government, was granted bail of €50,000.
The request also covers four other dismissed Catalan ministers who did not show up.
Spain has been in a constitutional crisis since the referendum was held on October 1 in defiance of a Constitutional Court ruling that had declared it illegal.
Last week, Spanish Prime Minister Mariano Rajoy imposed direct rule on Catalonia, dissolving the regional parliament and calling local elections for December 21.
This came after the regional government voted to declare the independence of the north-eastern region.
