LA PAZ, June 17 -- Russia was considering Bolivia's invitation to join the Group of 77 Plus China (G77+China), Bolivian ambassador to Russia Maria Luisa Ramos said Tuesday.

Ramos told reporters a "top level" Russian diplomat confirmed his government was considering the invitation made by Bolivia's President Evo Morales, whose country holds the group's rotating presidency.

"In Russia, it had significant resonance," Ramos said. "A top-level diplomat personally told me that they are studying with much affinity the invitation made by President Evo Morales to form part of the G77."

Russia believes "in the need to build a multilateral world," she said.

During the opening of last weekend's G77+China Summit in the eastern Bolivian city of Santa Cruz, Morales called on Russia to join the bloc, which represents more than two-thirds of United Nations (UN) member states, to help advocate "worthwhile" policies.

Bolivia, "through its leadership, is seriously contributing to the construction of a new multilateral world," Ramos said.

One of the duties of the members of the group was to help promote the final declaration of the G77 summit, the product of multilateral cooperation among the world's developing and emerging nations, she said.

The June 14-15 summit concluded Sunday with the adoption of a declaration that included commitments to eradicate poverty among member states, create a new world economic order and seek accords towards the UN-backed post-2015 Millennium Development Goals.
