fighter jets would land June 15 at the Indian Air Force (IAF) base in Tezpur, about 185 km north of Assam's main city of Guwahati.
"Four Sukhoi 30 MKI fighter jets would land first and soon it would be a full squadron comprising of 18 aircraft," Defence spokesperson Colonel R Kalia told IANS.
Capable of carrying nuclear weapons and tailor-made for Indian specifications, Su-30 MKI is a variant of the Sukhoi Su-30 jointly-developed by Russia's Sukhoi Corporation and India's Hindustan Aeronautics Ltd (HAL) for the IAF.
"There are more plans to improve infrastructure in the northeastern region, including developing four or five airfields and advanced landing grounds, besides putting our best assets in the region," a senior IAF official said requesting not to be named.
The decision to set up a squadron of the most potent fighter jet in service with the IAF follows repeated allegations of Chinese incursions in the northeastern state of Arunachal Pradesh in the last few years.
The IAF base at Tezpur is within striking distance from the Chinese border along Arunachal Pradesh.
According to union home ministry reports, there were about 270 'violations' by China on India's western, middle and eastern sectors in 2008, while there were 60 such incidents reported so far this year.
Beijing had in 2003 given up its territorial claim over the Indian state of Sikkim but was still holding on to its age old stand that a vast stretch of Arunachal Pradesh belongs to them.
The mountainous state of Arunachal Pradesh shares a 1,030-km (650-mile) unfenced border with China.
The McMahon Line, an imaginary border that is now known as the Line of Actual Control (LAC), marks the India-China border along Arunachal Pradesh.
India and China fought a bitter border war in 1962, with Chinese troops advancing deep into Arunachal Pradesh and inflicting heavy casualties on Indian troops.
The border dispute with China was inherited by India from British colonial rulers, who hosted a 1914 conference with the Tibetan and Chinese governments that set the border in what is now Arunachal Pradesh.
China has never recognised the 1914 boundary, known as the McMahon Line, and claims 90,000 sq km (34,750 square miles) -- nearly all -- of Arunachal Pradesh. India also accuses China of occupying 8,000 sq km (14,670 square miles) in Kashmir.
"Setting up of advanced air bases and plans to increase military strength in the region is to meet future national security challenges," an army commander based at the Four Corps Headquarters at Tezpur said on customary conditions of anonymity.
