Rumor has it: cross-Straits marriage between two brokerages---Oriental Morning Post

Guoyuan Securities yesterday refuted a report that the firm has inked an agreement with Taiwan's Concord Securities on stake transaction and strategic cooperation.

In a report released Thursday by Taiwan-based Economic Daily News, vice chairman of Concord Securities Zheng Dayu was quoted as saying, "Guoyuan Securities and Concord Securities have signed a strategic cooperation agreement to pave way for the former one to buy no more than 20 percent stake in Concord." He also said Concord Securities plans to issue new shares in the first half of next year to raise T$2 billion (US$ 61 million).

The report came as a coincidence with the signing of a memorandum of understanding between the mainland and Taiwan, allowing mainland China's financial institutions to conduct business in Taiwan starting next January.

Chen warned that the unusual inflowing poses a risk of forming an asset bubble, especially in the event of a US interest rate increase or a stronger US dollar.

IMF's head Dominique Strauss-Kahn and World Bank's president Robert Zoellick have both shown concerns about Hong Kong's real economy if the bubble bursts.
