While the UN interagency report demands a number of actions for sustainable oceans, Kyle announced that more than 80 nations, private companies and international organizations have declared support for an alliance known as the Global Partnership for Oceans.

Although only 13 nations have joined the GPO, Kyle believes support for the alliance will increase in the runup to the formal Rio+20 conference.

It is unclear whether China will join the GPO, but the State Ocean Administration was a co-sponsor of The Oceans Day on Saturday.

The challenges for sustainable growth along China's 18,000 kilometers of coastline have been huge. Excessive and disorderly fishing, artificial farming, the rampant discharge of waste into the ocean and repeated oil spills over the years have seriously damaged the ecosystem.
