Singh, who will lead a delegation, will hold consultations with Tajik Deputy Foreign Minister Nizomiddin Zohidov apart from calling on other Tajik dignitaries.
Foreign Secretary's visit to Tajikistan will focus on assessing ongoing bilateral cooperation and reviewing the implementation of projects decided during the visit of Tajik President Emomali Rahmon to India in 2012.
The bilateral relations between the two countries were elevated to strategic level during Rahmon's visit. Both sides had inked six pacts in several areas including business and trade, health, culture, sports and education during the visit.
Vice President Hamid Ansari had visited Tajikistan in April last year.
