The Japan Center for Economic Research released its so-called Li Keqiang index on Tuesday. The index is based on three economic indicators: railway freight, electric power generation and growth in bank lending. The Li Keqiang index showed that the Chinese economy expanded 4.8% to 6.5% in the second quarter, below the official 7% growth.
The Japan Center for Economic Research's data began to differ around summer 2013 and the gap widened.
