Brazil's BM&FBovespa and China's state-owned Shanghai Stock Exchange will sign an agreement on Monday that could open the door for future tie-ups between two of the world's largest exchange operators. The news comes after a frenzied week of announced mergers that show bourses are aggressively strengthening global ties in the face of competition at home. Any significant Brazil/China tie-ups do not appear imminent, however, as they would require the launch of the so-called international board in Shanghai, planned for later this year. Foreign companies are currently not allowed to list in the mainland and Shanghai's membership structure precludes any equity deals at this stage.
