RIO DE JANEIRO (Reuters) - Brazilian Finance Minister Fernando Haddad said on Thursday that G20 finance leaders were poised to endorse a joint declaration on international tax cooperation addressing issues such as the taxation of super-rich individuals.

"I like to see the declaration not as the end of a journey, but as a starting point," said Haddad in his public remarks opening a discussion of taxation with his counterparts. He also called on the group to "advance towards a coordinated global minimum tax on billionaires" - a proposal Brazil has pushed with its presidency of the Group of 20 major economies this year.
