KATHMANDU: Foreign affairs expert Bhekh Bahadur Thapa on Wednesday said Prime Minister Pushpa Kamal Dahal's upcoming India visit should not be portrayed in a negative light. Speaking with journalists in Kathmandu on the eve of PM Dahal's departure to India, Thapa said the visit could be an attempt to improve the bilateral relations and elevate it to a new height. 'The Nepal-India relation should now move ahead on the basis of trust,' Thapa, who also leads the bilateral Eminent Persons' Group on behalf of Nepal, said, 'Every matter should be discussed openly.' The former foreign affairs minister also informed that the EPG was working to review various bilateral treaties including the 1950 Peace and Friendship Treaty. Thapa also praised the current government for sending Minister for Foreign Affairs Prakash Sharan Mahat to prepare for the PM's visit. PM Dahal is scheduled to embark on a four-day state visit to the southern neighbour on Thursday.
