India on Thursday expressed disappointment with the “weak” political will of developed countries to provide developing nations with enhanced means to implement objectives of Green Economy, which it said will also be a “green-wash” if the process is not democratised.

As around 100 world leaders, including Prime Minister Manmohan Singh, gathered here for the Rio+20 Summit, India also firmly rejected unilateral measures and trade barriers under the guise of Green Economy, which was the buzz ahead of the deliberations here.
