"The solution might include the devolution of power," Minister Gunasekara said.
The much-talked about All Party Representative Committee (APRC) will be re-convened to discuss the proposals.
However, President Mahinda Rajapaksa has earlier dismissed all efforts that have been made so far to find political solutions to the country's ethnic problem.
Mr Rajapaksa has now said he does not think any generally acceptable solution has yet been suggested, so "after the present election I am going to put forward my own solution to the problem" he told BBC's Charles Haviland in Colombo.
He has remained vague on what this means although he has spoken of a possible upper house of parliament.
The APRC convened in 2006 claiming to 'reach consensus on a package of measures to guarantee the rights of Tamils,' is yet to hand over its proposals.
