The Economist provides a brief summary of seemingly everything. It is a bit of a struggle to get through it each week though. Sometimes I question how much I really care about China's economic policy. Sometimes they publish some really fantastic articles though. Much less chaff than most online news sources.
I'd recommend that everyone reads at least a few issues of the New Yorker. Some of the long-form reports in there are absolutely fantastic - the kind of article that you still think about months or years after reading. A subscription might just result in mountains of unread magazines though.
