The memos were signed by London Exchange President Chris Gibson-Smith, MICEX General Director Aleksandr Potemkin and RTS President Vladislav Streltsov, the London Stock Exchange's press service told RIA Novosti.
The co-operation agreements are designed to intensify information exchanges, promote long-term, mutually beneficial relations between the two countries' financial markets and properly run securities markets in these countries.
"The signing of the memo proves that MICEX has been recognised as Russia's leading non-governmental organisation trading in securities," noted Mr Potyomkin.
"The exchange of information on securities will speed up the Russian stock market's integration into the international capital market," said Mr Streltsov.
