Vienna - Hollywood star Sean Penn is suggesting that efforts to help Haiti recover from last year's devastating earthquake are being hampered by a lack of cooperation and communication between aid groups.

The two-time Oscar winner co-founded the Jenkins-Penn Haiti Relief Organization in the wake of the Jan. 12, 2010, disaster and has personally taken part in projects on the Caribbean island.

Penn told reporters in the Austrian capital Tuesday that "there's far too much duplication, far too little communication" between organizations and that there are "competing cultures in the international relief world."

He also said Haitians were still experiencing "enormous trauma" and that he's approached every day by people who, first and foremost, want jobs.
