The collaboration may include cross-listing shares and sharing technology and new products. Joint investment is not being discussed at this stage and there are no plans for a full merger, according to TSE spokesman Mitsuo Miwa.
The TSE is also expanding its links with the Shenzhen Stock Exchange, and may approach the Shanghai and Taiwan exchanges. It has also suggested that it could form links with NYSE in the event of a NYSE/Euronext merger.
Similar talks are going on between Japan’s securities exchange Jasdaq and New York's Nasdaq, which may also cooperate on cross-listings.
