Since work is likely to continue towards solving the final row of the puzzle later, what matters is locking in progress in cracking most of the solution.  Getting the final row done feels very satisfying, but more critical is working out how to get the lion’s share of the rows into place. This is true, even if it turns out that the final rows can’t be slotted into place using the existing directions for solving the puzzle.  It will still push forward trade across Asia in ways that have not been tried in the region before and deliver economic benefits to companies and consumers.   Getting to the end, however, remains a challenging goal.  Solving a “normal” Rubik’s cube with four sides is hard enough.  Completing one with 16 sides is testing the patience and negotiating skills of everyone involved.
