Maybe the Venezuelan president just decided he didn't want part of New Jersey anymore. From El Universal:
"CITGO planned to given the island to the U.S. since 2004 to carry out an environmental cleanup of the area and transform the site into a wildlife refuge.

Petty's Island has approximately 392 acres and is in the Delaware River, off the coast of Camden City (the poorest city in the U.S.).

...After Venezuela gives the island to the US, it will be transformed into a wildlife refuge, thanks to the flora and fauna diversity of the region, some of them endangered species.
