Speaking at a program here, Sangma said the previous strategy of seeking the Centre's intervention "did not" yield results.
He said his government has submitted all the records, maps and notifications to the Assam government to stake claim over the disputed areas.
The chief minister also informed that recently a meeting between the chief secretary of the two states was held in a cordial atmosphere and Assam government had sought for some more time to study Meghalaya's documents.
He said Assam was not agreeable with Meghalaya's proposal asking the Centre to set a Boundary Commission in solve the boundary issue of the two neighbouring states.
"An all party boundary committee was formed and the state Assembly unanimously passed the resolution for Centre's intervention," Sangma said adding that the idea was rejected by the Assam government.
The Chief Minister informed that Meghalaya was having twelve areas of difference with Assam and the previous governments had done "very little" over the years.
Sangma said earlier, the government could not build a strong case while making its claim on border issues as the Assam government was demanding documentary proofs.
"Border issue should not be use for political mileage and peaceful atmosphere should be allowed to exist, so that the issue could be amicably solved," he said.
