The international aid organization Oxfam says Asia's overall recovery from last year's tsunami is moving ahead, but rebuilding efforts have been uneven.

An Oxfam study Monday says one of the most persistent problems has been providing permanent shelter to those who lost everything last year in the devastating earthquake and mammoth ocean waves that hit coastal areas of Indonesia, Sri Lanka, Thailand, India and other countries.

The report adds that 60 percent of all those whose jobs were swept away by the tsunami last December 26 have now returned to work.

Jeremy Hobbs, Oxfam's executive director, says the most impressive aspects of the tsunami recovery have been the resilience of the tsunami victims and the generous response by ordinary people worldwide to appeals for help.
