On October 15th, 2010, Miguel Saiz's government and a 'Chinese State Company' â�� Heilongjian State Farms - reached an agreement for irrigation rights, access to the San Antonio Port, and to lease 320,000 hectares in the Rio Negro Valley, Argentia.
The land is relatively arid and at the time of the agreement was covered in native vegetation grazed sparsely by local farmers' cows.
$20 million was immediately invested by the Chinese companies to install irrigation and test the plots. No environmental impact study or public hearings took place before the agreement, which violates multiple national statues.
Environmental organizations, citizens, and government officials together legally opposed the project, which the judge of the Superior Court of Justice of the province upheld on November 24th, 2011 nullifying the agreement.
