The US Department of Interior says officials of the United States administration are holding a conference about how to react to the Marshall Islands bid for more US compensation.
The US carried out 67 nuclear tests in the islands.
The director of the office of insular affairs, Nick Pula, says some US officials are in Hawaii to discuss these issues.
"These were just officials of the state department, the interior department, health and human services and I think the energy department as well. They are just internal conversations regarding their programmes or existing programmes in trying to respond to some of the issues that were raised by the Marshall Islands."
The US paid compensation under previous agreements, but the extent of the health problems related to the tests has been bigger than expected.
