World leaders struggled Monday to inject confidence for the global economy into the G20 summit in Mexico dominated by a spiraling European debt crisis that is troubling markets and paralyzing growth.

The heads of the 20 biggest economies welcomed Greek voters' decision to back parties that are committed to the terms of their European Union and IMF-led bailout, but there was no respite for the eurozone from the markets. G-20 leaders will honor the commitment of over 430 billion US dollar capital injection into the IMF in order to prevent the European debt crisis from continuing to spread. Earlier, leaders from BRICS - Brazil, Russia, India, China and South Africa, met to agree on financial and international key economic issues. G-20 leaders are expected to approve the Los Cabos action plan to boost economic growth, employment and trade while decreasing budget deficit.
