Reporting from Beijing — Youku Inc., China’s leading online video site, reached an agreement to merge with its smaller competitor, Tudou, in a stock deal between the two New York-listed companies worth more than $1 billion.
The deal, which was announced Monday, creates an unlikely partnership between two companies that have struggled to turn a profit in China’s booming Internet space. The two websites have long been bitter rivals, fighting in court over alleged copyright infringement.
