Nomura Securities Co. and Rothschild said Tuesday they have created an alliance to pursue opportunities in cross-border mergers and acquisitions between Japan and Europe.

"The alliance will contribute to increased activity in Japanese-European advisory business for both firms, building on Nomura's extensive corporate client relationships in Japan and Rothschild's leading position in European M&A," the firms said in a statement.

Nomura Securities, a wholly owned subsidiary of Nomura Holdings Inc., is Japan's largest brokerage. Rothschild is one of the world's leading independent investment banking groups.

With the alliance with the major Anglo-Franco financial group, the Nomura group can establish an M&A network linking Japan, Europe and the United States, industry officials said.

Nomura Securities has already formed capital and business tieups with U.S. investment bank Thomas Weisel Partners group.

Rothschild has more than 40 offices in 33 countries and was ranked No. 1 in European M&As in 2004, with the value of its announced deals estimated at $211.8 billion.
