          An absolutely jaw-dropping achievement of emergency civil engineering. That was the best use of anti-tank military hardware imaginable (initial channel widening Monday night) and explosives use Monday, Tuesday and early this morning by a military engineering unit. The Chinese engineering spokesmen weren't understating the delicacy of charge placement, timing and energy release, given the highly unstable soils at the site.

          Kudos to the FT team covering this story.
