NEW DELHI : China's Oppo cancelled the live online launch of its flagship smartphone in India on Wednesday after a border clash between the two countries that has renewed calls from local Indian trader groups to shun Chinese products.Soldiers from India and China fought each other with nail-studded clubs and stones on a disputed Himalayan mountain frontier this week, leading to the death of 20 Indian soldiers in the worst clash since 1967.The clashes risk souring sentiment for big Chinese investors who were eyeing the Indian market and already faced pressure as anti-China sentiment festered during the coronavirus outbreak.Chinese firms such as Great Wall, SAIC and Bytedance have placed major bets on India, where investors like Alibaba also.
