I realise that the OP is on tour, and if he's in China, replacing the frame before the tour is over might be out of the question, which is a shame. Still, the advice to ship any unneccessary weight home is very good, as is slowing down. Maybe turn the 9 days to 12 days, for the sake of safety. Once you're home, try to warranty the frame. Surly probably won't accept it, but it's worth a shot. Either way, *replace* the frame. Don't putz around on it unloaded; you'd probably be fine, but why risk your safety for a frame that retails, new, for 420USD? And, for the record, steel *can* fail catastrophically. I know of a guy who lost a whole head full of teeth and broke his jaw when his 631 jamis exile snapped. Be careful with that thing while in China, then replace it asafp.
