VALE is “reevaluating” its potash project in Argentina in light of the recent YPF expropriation; the project previously run-ins with the local government, but now it’s hard to see why VALE would want to go forward under any circumstances:
[CEO Murillo] Ferreira said Vale is also "reevaluating its Rio Colorado project in Argentina over inflation fears and political risks."
The concession for the $4.6 billion Rio Colorado potash project was suspended in the middle of 2011 when the provincial government of Mendoza accused Vale of failing to comply with local labor laws.
