Bolivia's President Evo Morales (R) arrives at the summit. Bolivia is playing an increasingly important role in the climate negotiations by leading attempts to force developed countries to slash their emissions further than they have so far pledged. It was one of seven countries that refused to sign up to the deal that emerged from Copenhagen, incurring the wrath of Britain and the US, which this month withdrew $3.5m of climate aid from Bolivia
