'The scheduled visit of a parliamentary delegation to the project site has been deferred,' an official at the parliamentary standing committee on water resources ministry told New Age newspaper Sunday.
The all-party delegation was to visit the Tipaimukh project site July 15. The fresh date will be fixed once Sheikh Hasina returns from Egypt July 17, the official said.
Zia had, in the early 1990s, raised at the UN General Assembly the dispute with India over the sharing of waters of the Ganga, another major river system the two South Asian neighbours share.
The bilateral Ganga Water Treaty was signed in 1997 and the dispute was settled during Sheikh Hasina's earlier tenure as the prime minister.
Hasina told parliament earlier this month that she intended to resolve the new dispute as well through talks.
