New Delhi, Sept 20 (ANI): The Congress alleged that Prime Minister, Narendra Modi, did not take the issue of incursion by the Chinese army with President Xi Jinping strongly enough. Congress leader Salman Khurshid, said Modi's stand on the issue was rather weak. Chinese troops as well as civilians transgressed the de facto but disputed border with India that overshadowed ongoing President Xi Jinping visit to New Delhi. Khurshid said Xi invited Congress president, Sonia Gandhi, vice president, Rahul Gandhi and former Prime Minister, Manmohan Singh to visit his country.
