In the backdrop of ongoing protests across the country against the amended Citizenship Act, Chinese Consul General to Kolkata, Zha Liyou, said it is an internal matter of India. The problem has to be resolved by India alone, he said. "It's an internal matter of India. We have nothing to say on it. It's your country and you have to resolve your own issues," Liyou told reporters at the sidelines of a programme here.
