Here is Paul Blustein:
Someday historians may look back on 2010 as the year the global trade system died -- or contracted a terminal illness. A pledge by world leaders to complete the Doha round of global trade negotiations this year looks increasingly likely to end in yet another flop, and that would deal a crushing blow to the trade system as we know it.
After eight painful years of standstill and failure, with each meeting just a shoveling of intractable problems forward to the next, the Doha talks might collapse once and for all in 2010, possibly taking the World Trade Organization (WTO) down in the process.
If Doha falls apart, the WTO's ability to continue performing its vital functions would be imperiled. If it can't forge new agreements, how long before it loses its authority to arbitrate disputes? The trade body won't disintegrate overnight, but the danger is that its tribunals will be weakened to the point where member countries start ignoring WTO rulings and flouting their commitments.
