Switzerland and Liechtenstein have agreed to help fund a study into how terrorism is financed.
The study by the Watson Institute for International Studies at Brown University in the United States will investigate channels through which money reaches terrorist organisations such as al-Qaida.
A United Nations team monitoring movements by al-Qaida and the Taliban had called for the investigation.
The Swiss and Liechtenstein authorities will each provide SFr50,000 ($42,000) toward the project and the World Bank will contribute SFr40,000, according to Switzerland's ambassador to the United Nations, Peter Maurer.
Maurer added that Switzerland, which has been under scrutiny in the United States over its banking secrecy laws, was committed to effective measures against the financing of terrorism.
The country has funded a UN working group on the issue for the past two years, he added.
