Pakistan's high commissioner-designate to India Aziz Ahmad Khan will leave for India on June 30 to take over his new posting.

His counterpart, Shiv Shankar Menon, is expected to take over his posting in Islamabad in the second week of July. Menon, who will shortly relinquish his present post as India's ambassador to China, is currently tied up with Prime Minister Atal Bihari Vajpayee's visit to Beijing.

He is expected to wind up his stay in Beijing towards the end of the month and begin preparations to reach Islamabad by second week, Indian diplomats said. 

Earlier, Aziz Khan had hinted that he planned to go by the first bus to India if the two countries managed to restore the bus service by that time. Already Pakistan government has said that Prime Minister Mir Zafarullah Khan Jamali may inaugurate the first bus from Lahore to New Delhi.

Officials said while the two countries have sorted out most of the issues relating to the restoration of the bus service during this week's visit of Pakistan delegation to India, the two sides were now focusing their efforts to address related issues such as granting of visas and arranging new buses to run in the Lahore-New Delhi route.
