Struggling Toshiba Corp. said Tuesday it is considering selling a majority stake in its U.S. nuclear unit, Westinghouse Electric Co., aiming to stem further losses from its troubled nuclear business.

¡°How we can shut down the risk from the overseas nuclear business is a big issue for us,¡± Toshiba President Satoshi Tsunakawa said during a news conference at the company¡¯s headquarters in Tokyo.

Chinese firms are likely to show interest in Westinghouse because more reactors are expected to be built in China, some experts have said. It¡¯s unclear, however, whether the U.S. government would allow such a sale.
