The basic principle of Nepal's foreign policy is to maintain close and harmonious ties with both India and China with whom it has commercial and cultural relations, Deputy Prime Minister Krishna Bahadur Mahara said on Tuesday. "We have extensive political, economic, commercial and cultural relations with both the neighbours," Mahara, who is also the foreign minister, said while talking to a team of National Defence College of Bangladesh at his office here. Nepal's relations with its neighbouring countries (India and China) in south Asia have remained strong, warm and friendly, he said.The visit of the Bangladeshi team is a reflection of the close and cordial relationship between Nepal and Bangladesh, which is marked by profound goodwill, cooperation and understanding, Mahara said."We do not compare our relations with one country with that of the other. Bases and factors determining friendship and cooperation are different for each country and each bilateral relation is unique," the deputy prime minister said.
