1999-Present: 40 years old dispute of Telangana state's claim over several villages in Chandrapur district comes back to limelight. The Telangana High Court declared these villages to be part of their state. In response, the Maharashtra government had moved it to the Supreme Court, where its appeal is still pending. 14 villages in Jiwati taluk, 12 villages in Rajura taluk and 5 villages in Antapur of Chandrapur district are disputed with Telangana State. They are revenue villages of Marazoda, Anarpally, Lakampur, Ananthapur, Esagaon, Bolapathar, Gouri (D), Parandoli, Paraswada, Arkepally (D), Karanjiwada, Kota, Mukadamguda, Maharajguda, Lendijala, Lendiguda, Indiranagar, Yesapur, Narayanguda, Shankarloddi, Padmavathi and Janakpur, etc sharing border with Adilabad District of Telangana, which has laid claim on these areas. The encroachment by Telangana is much attributed to its two humungous projects Pranahita Chevella lift irrigation scheme and Icchampally project which are seen to drain-out the water, land, people and agricultural resources of Vidarbha region.
The ongoing Telangana State Irrigation project Pranahita Chevella lift irrigation scheme which is a project not in the interest of Maharashtra. Maharashtra will be losing about 2123.4 hectares of land (which is severely under reported by print media at 1500 Ha or even less).
The Telangana State Irrigation project Icchampally Project which is a project not in the interest of Maharashtra. Maharashtra will be losing 33,614 hectares of land which is more than 100 villages.   
2011-present: Disputes between Belgaum's Marathi-speaking leadership and the Karnataka government became frequent. Matters came to a head in mid-2012, when the Karnataka government actually superseded the Belgaum City Municipal Corporation. The Maharashtra Legislature unanimously passed a resolution against the move and demanded that Belgaum and the surrounding area embroiled in a border dispute be placed under the rule of the Centre until resolution of the dispute in the Supreme Court. Only in late 2011, the Belgaum civic body was dismissed along with its Marathi-speaking mayor and deputy mayor. From the 1960s, when the border dispute began, until 2015 the Maharashtra legislature passed at least 18 resolutions against the Karnataka government, calling its actions to crack down upon Marathi-speaking institutes and people in Belgaum illegal and unjust.
