"China should not continue claiming Arunachal unnecessarily as the state is an integral part of India," Mithi told PTI.
Welcoming the visit of External Affairs Minister Pranab Mukherjee to China beginning today, Mithi said a good neighbourly relations with Beijing was important for overall development of the state.
Mithi was administered oath as a member of the Upper House by Chairman Hamid Ansari on Wednesday.
"The boundary issue should be resolved immediately. A solution to the vexed issue will help development of the bordering areas," Mithi, who was till recently the Governor of Puducherry, said.

India says China is illegally occupying 43,180 sq km of Jammu and Kashmir including 5,180 sq km illegally ceded to Beijing by Islamabad under the Sino-Pakistan boundary agreement in 1963. On the other hand, China accuses India of possessing some 90,000 sq km of Chinese territory, mostly in Arunachal Pradesh.
Mithi said his state does not have a proper telecommunication and road network and vowed to do "everything possible" to ensure speedy development of the state.
