Indonesia and Switzerland agreed here on Thursday to avoid double taxation by signing an amendment of the document on protocol for avoiding double taxation. "This agreement is an important step to increase economic relations between the two countries especially to create a more conducive atmosphere for investment in Indonesia," Swiss ambassador to Indonesia, Bernadino Regazzoni, said after the signing of the document at the foreign ministry. He welcomed the arrival of Swiss Confederation President Micheline Calmy-Rey for the first time in the country on Wednesday for a three-day visit. He said this was the right time to increase the two countries' bilateral relations in the political as well as economic fields. The Indonesian foreign ministry's director for West European Affairs, Ramli Sa'ud, said that the amendment was done to adapt with the current situation. "In principle, goods already taxed in Indonesia may not be taxed again in Switzerland and vice versa," he was quoted as saying by Indonesian news agency "Antara."
