Official sources said Menon was in Dhaka for a few hours to review the latest developments linked to Singh`s September 6-7 tour.
"Mr Menon held meetings with Water Resources Minister Ramesh Sen and Prime Minister Sheikh Hasina`s foreign affairs adviser Gawher Rizvi and Economic Affairs Adviser Mashiur Rahman," a source told PTI without any elaboration.
The source said, Menon represented the Indian Water Resource Minister P K Bansal in the meeting with Sen whose counterpart was expected in Dhaka ahead of Singh`s visit as Dhaka and New Delhi are set to ink a deal on sharing of waters of Teesta river coinciding with the meeting between the two Prime Ministers.
Earlier, the NSA had come to Dhaka on August 28 on a two day tour and held extensive talks with Bangladesh leaders, including Hasina to fine tune agreements, MoUs and protocols that were expected to be signed during Singh`s visit. The issues discussed included connectivity, trade, power, border, water, security and culture.
In related development, Indian security officials today held extensive meetings with their Bangladesh counterparts at the Prime Minister`s office on issues related to Singh`s security during his tour, officials said.
"They held long meetings and reviewed the security arrangements," an Indian High Commission spokesman told PTI.
