Nerval's Lobster writes "Dropbox has renewed access to the Chinese market for the first time in four years. But why? The Chinese government first blocked access to Dropbox in 2010, most likely to prevent people within China from sharing data via the cloud. Now Dropbox is back online in China, albeit at slower speeds. Despite repeated queries from Slashdot, however, Dropbox has declined to comment on why China may have dropped the in-country restrictions to its services. "We still have nothing to share," the company responded after the third email. Dropbox isn't the only foreign cloud service available on the Chinese market (although Google Drive remains blocked): in late 2013, Amazon announced it would open an Amazon Web Services (AWS) region in the country; at the time, the Amazon Web Services Blog alluded to the "legal and regulatory requirements" that this new AWS region will obey. So questions remain: Did Dropbox know it would regain entry to the Chinese market? If so, did it need to agree to certain conditions before the Chinese government would "flip the switch," as it were?"
