New Delhi/ Chushul, Sep 16 (ANI): India is cautiously optimistic ahead of Chinese President Xi Jinping's visit that will seek to allay mutual suspicions and spur economic ties between the Asian giants, with hopes of high investment deals to narrow a yawning trade deficit. Xi Jinping will arrive in Gujarat on Wednesday when Prime Minister Narendra Modi will be marking his 64th birthday. New Delhi and Beijing have a complicated relationship marked by growing economic ties but also distrust, particularly over their unresolved territorial disputes. However, international relations experts like Srabani Roy Choudhury, say the bilateral growth cannot be driven by the two personalities alone as there is a significant trust deficit that needs to be overcome. Congress leader Shashi Tharoor, said the major business delegation accompanying Xi could pledge mega deals during the trip. However, another Congress leader Manish Tewari, questioned Beijing's intentions in the wake of recent reports of Chinese incursions on the disputed Himalyan border.
