The first formal meeting between the Pakistan government and a Taliban-nominated team has begun in an undisclosed location, local media say.
They are due to start charting a "roadmap" for peace talks.
The talks were delayed earlier in the week after the government side asked for clarification about the composition of the Pakistan Taliban team.
Militants from the Tehreek-e-Taliban Pakistan (TTP) have been waging an insurgency inside Pakistan since 2007.
The talks initiative was announced last week by Prime Minister Nawaz Sharif, following a spate of attacks.
