Most advanced economies are showing signs of strengthening recovery, the OECD has said, highlighting growth in Japan, the US and Britain.

The Organisation for Economic Cooperation and Development said its monthly composite index of leading indicators of economic activity "point to economic growth firming in Japan, the US and the UK."

The index for Canada "indicates a positive change in momentum," the OECD said.

The euro zone, including France and Italy which are a cause of concern to some analysts, continued to show a positive change in momentum.

Germany was pushing forwards towards greater growth, the OECD noted. 

"In the emerging economies, the CLIs point to a tentative positive change in momentum in China, to growth around trend in Brazil and Russia, and to growth below trend in India," the OECD said.
