The steel business faces its biggest hurdle in 60 years with some analysts predicting double digit production cuts in 2009. Now, a sudden change in China trade policy may spell even more trouble for Western steelmakers, as Beijing is currently considering measures to shore up its ailing steel industry with new export policies.

Baosteel Group Corp., China’s largest steel producer, will pay $4.2 billion in cash for an 80% stake in a new Guangzhou-based steel mill that will merge two rivals, Shaoguan Iron & Steel Group and Guangzhou Iron & Steel Group.

China is already the world’s top steel consumer and producer, churning out one-third of the global supply. This newly formed company, Guangdong Iron & Steel Group Corp., will boost Baosteel’s capacity by 33% to 40 million tons.
