Thanhawla held an hour-long meeting with Sonia Gandhi at her residence in New Delhi Friday and apprised her about the state's financial problems, an official of the chief minister's secretariat told reporters Saturday.
The state government had earlier submitted a proposal to central government seeking Rs.500 crore for payment of increased salaries to its employees after the implementation of sixth pay commission recommendations.
According to the official, Thanhawla also apprised the Congress chief about political developments in the mountainous state.
He also requested Sonia Gandhi to extend her support on the proposal to increase posts of Indian Administrative Service and Indian Police Service officers in Mizoram.
The Congress-ruled northeastern state, which shares 318 km with Bangladesh and 404 km with Myanmar, will go to the polls later this year.
