New Delhi: Chinese defence firm Avic Chengdu Aircraft, the maker of J-10 fighter jets which were used by Pakistan against India during the conflict, has seen its share price crashing almost 12 per cent. The sharp drop in its stock came after the Prime Minister Narendra Modis speech upon the successful completion of Operation Sindoor which resulted in a decisive victory for India. Shares of Chinese defence companies faced a heavy selloff this week while Indian defence sector stocks surged.
