President Xi Jinping is expected to hold his first meeting as China’s new leader with Prime Minister Manmohan Singh this week, along the sidelines of the March 26 BRICS Summit in South Africa. The talks — they are expected to be a brief event according to officials in Beijing, who cited the limitations of Mr. Xi’s “tight schedule” — will mark India’s first major engagement with the new Chinese leadership, which took over following the conclusion of the National People’s Congress, or Parliament, on March 17.
