First, the Chinese economy is currently growing at its slowest rate in three decades.
Some investors might assume that Facebook's lack of a presence in China indicates that it hasn't made any money in the People's Republic over the past decade.
That requirement increases Facebook's number of business pages, which surpassed 60 million in late 2016, and allows Chinese companies to directly communicate with overseas consumers.
Bringing China's advertisers to those developed markets could offset that slowdown.
Facebook is also reportedly taking major Chinese clients on trips to India and the Middle East, and suggesting that those regions -- which generate stronger active user growth than its Western markets -- offer additional marketing opportunities beyond the United States.
But like Facebook, Google still remains active in China through experimental apps, partnerships, and investments.
