Amendment incorporates Warehousing and Commercial operations into Sector Specific Special Economic Zones and Special Economic Zones for Free Trade and Warehousing, and expressly pairs those entries with the proviso Such other operations which the Board of Approval may authorize from time to time, thereby listing warehousing and commercial activity as authorized operations and preserving the Board of Approval's discretion to authorize additional operations.
