JERSEY CITY, N.J. (AP) The owner of New York City's World Trade Center has approved incentives for the building where 21st Century Fox and News Corp. are considering leases.

The Port Authority of New York and New Jersey announced Thursday approval of changes in a lease agreement for 2 World Trade Center.

Twenty-First Century Fox and News Corp. are considering renting about 1.5 million square feet. The agency says the deal will move forward with a $19 million contribution from the developer Silverstein Properties and $9 million from the authority.

The authority oversees the region's airports, bridges and tunnels and owns the trade center site.

Silverstein, News Corp. and 21st Century Fox did not immediately respond to messages seeking comment.

The concessions mark a shift from earlier declarations that there would be no public sector support for the building.
