Accompanied by his Deputy Babbar Amin, Bashir said this was his first visit to the eastern state and he was really impressed with what had been demonstrated to him about the state.
Kumar will head a 12-member delegation of ministers and officials from the state to Pakistan from November 9-16. He is going there on an invitation of chief minister of Sind and Punjab provinces.
He is scheduled to visit Karachi, Lahore and Islamabad and return by road through the Wagah border.
Asked if Pakistan would have increased trade engagements in Bihar, Bashir said many significant things would emerge in after the Kumar's visit.
A Pakistani Parliamentarians' delegation to Bihar in August this year had heaped rich praise on the chief minister and commended his success in bringing a turnaround in the state.
To a question on Ajmal Kasab, the only terrorist captured alive after the attacks in Mumbai in 2008, Bashir said "it is a judicial process."
Asked about some unpleasant events in the recent times of Pakistani boys leaving Indian brides after marriage and returning to their country, Basir said "there are still many irritants which need to be tackled."
Bashir and Amin accompanied by bureaucrat-turned JD(U) MP NK Singh later went to see Patna museum, Buddha stupa and Khuda Bakhsh Oriental Public Library, which holds a unique repository of 21,000 oriental manuscripts and 2.5 lakh printed books.
