When Prime Minister Narendra Modi undertakes a bilateral visit to Nepal on 3-4 August - the first by an Indian premier in 17 years since IK Gujral in 1997 - the most important and sensitive agenda of his Mission Nepal won't be purely bilateral. China will be the gorilla in the room during Modi's one-to-one conversations with his Nepalese interlocutors. And much of it is unlikely to be shared with the media, now or ever. External Affairs Minister Sushma Swaraj has done the preparatory work for Modi's visit to Kathmandu in her just-concluded visit to Nepal. It is not for nothing that Nepal is the second SAARC country Modi has selected for paying a bilateral visit to so early in his tenure after making Bhutan the destination of his first foreign visit. Both Bhutan and Nepal share border with China - 470 kms and 1111 kms respectively. Both these SAARC countries are strategically crucial for India and in both China has been enlarging its strategic footprints phenomenally. The Chinese influence in Nepal has already become considerable to the point of rivaling the hitherto unchallenged clout of Indian embassy in Kathmandu which India has traditionally enjoyed for decades. True, India cannot complain about the rising graph of China in Nepal. But it is definitely a major concern for India's Nepal policy makers.
