A team of the Financial Action Task Force has visited the Marshall Islands, with both the FATF and local officials declining comment.
The visit to Majuro was to review progress on the Marshall meeting the FATF requirements on fighting money-laundering.
Ahead of the team's visit, the Marshalls parliament passed Banking Act amendments to give greater authority to the banking commissioner to impose fines and penalties for institutions that do not comply with new reporting procedures.
Last month, Marshall Islands officials said they hoped a successful review would lead to the country being taken off the blacklist of unco-operative countries.
One source says the Marshalls has been kept on the list amid suspicion over the business dealings of some Asians in Majuro following a government scheme to sell passports to mainly Chinese people.
