China today appreciated India's support and assistance for relief efforts in its earthquake devastated areas as New Delhi sent another batch of supplies as part of its first ever major humanitarian help to its giant neighbour. Beijing's words of appreciation were conveyed to India's Ambassador Nirupama Rao by Chinese Foreign Minister Yang Jiechi during her visit to the Foreign Office to write in the condolence book opened for foreign diplomats today as the country began a three-day national mourning in memory of the earthquake victims. Yang noted that External Affairs Minister Pranab Mukherjee had personally conveyed the sympathy and condolences of the people and government of India during the meeting of Foreign Ministers of Brazil, Russia, India and China (BRIC) at the Russian city Yekaterinberg last week, Indian embassy officials said.
