US @SecPompeo sought EAM @SushmaSwaraj understanding, and they agreed to identify new mutually convenient dates to hold the Dialogue at the earliest, in India or the US. 2/2, he said in another tweet.
This new dialogue format was agreed upon between the two sides during the visit of Prime Minister Narendra Modi to Washington in June 2017.
After June last year, the two countries have tried to schedule the dialogue many times with several dates having been considered.
Earlier this year also, the '2+2 dialogue' had been postponed due to uncertainty over the confirmation of Pompeo as President Donald Trump's new Secretary of State. Pompeo was later confirmed as Secretary of State in April.
The dialogue is seen as a vehicle to elevate the strategic relationship between the two countries.
The meeting was expected to focus on strengthening strategic, security, and defence cooperation.
