China and India have worked together to produce films together, such as Kung Fu Yoga with Jackie Chan in the lead role.  However, the disruptions have increased again because China has built trade routes, the China-Pakistan Economic Corridor, with Pakistan on the territory of controversial Kashmir.  On June 16, 2017, Chinese troops began expanding an existing road in Doklam to the south with construction vehicles and road equipment, an area claimed by both China and India`s ally Bhutan.       On June 18, 2017, some 270 armed Indian troops and two bulldozers entered Doklam to prevent Chinese troops from building the road.     China has notably accused India of unlawful intrusion into its territory, through the Sino-Indian border, and of violation of its territorial sovereignty and the UN Charter.  India has criticized China for changing the status quo, in violation of an agreement reached between the two governments in 2012 on tripartite cross border points, and for creating «security problems» widely seen as referring to the Siliguri Strategic Corridor.   Indian media reported that on 28 June, Bhutan launched a process calling on China to stop building roads in Doklam and maintain the status quo.  Indian Foreign Minister Sushma Swaraj said that if China unilaterally changed the status quo from the point of convergence between China and India and Bhutan, it would pose a challenge to India`s security.  China has repeatedly stated that India`s withdrawal is a precondition for sound dialogue.   On 21 July 2017, Indian Foreign Minister Sushma Swaraj said that India and China should withdraw their troops for dialogue.
 On August 2, 2017, the Chinese Ministry of Foreign Affairs issued a document claiming that Indian border forces had illegally crossed the China-India border and explained China`s position on the matter.     The document states that China informed India of its plan to build roads in advance, «in full reflection on China`s goodwill.»  The Indian Ministry of Foreign Affairs responded by referring to its previous press release on this subject, contrary to a point-by-point rebuttal.  On August 28, 2017, China and India agreed to end the closure of the borders. Both said they were ready to withdraw from the Doklam impasse.

Chinese Prime Minister Wen Jiabao made an official visit to India from 15 to 17 December 2010, at the invitation of Prime Minister Manmohan Singh.  He was accompanied by 400 Chinese business leaders who wanted to sign commercial contracts with Indian companies.  During this visit, Prime Minister Wen Jiabao said: «India and China are two most populous countries with old civilizations, the friendship between the two countries has a venerable history that goes back 2000 years.»  30How have bilateral trade between China and India not been affected by policies? Have the latter developed a separation from their political-strategic skepticism or do the two remain fatally linked? The China-India interaction after the Indian nuclear tests of May 1998 is again an ideal case for such an analysis.
