One hundred pounds of China was exchanged with one hundred pounds of the United States. The biological, social and political repercussions of moving land are explored in the sculpture.

Each piece of land was sterilized with heat to prevent transportation of non native biological pests to its new location. After the exchange took place microbes, seeds and other life from the surrounding area gradually colonize the lifeless soil until the foreign soil is identical to the domestic soil. Documentation of the project and the soil was exhibited in an installation at the National Academy of art in Hang Zhou, China.

The US Department of Agriculture collaborated by quarantining and confiscating the Chinese soil upon arrival in the US despite a soil importation permit. They completed the piece by sterilizing and disposing of the soil in the US.
