The presidents of Afghanistan, Pakistan, and Turkey are meeting for talks in Turkey.
Turkish President Abdullah Gul is hosting the two-day trilateral meeting in Ankara, which is expected to focus on economic and security cooperation.
Afghan President Hamid Karzai plans separate talks with Pakistani President Asif Ali Zardari.
They are expected to discuss the suicide bombing last week that wounded Afghan intelligence chief Asadullah Khalid.
Karzai said on December 8 that the suicide attack was planned in the Pakistani city of Quetta.
He did not directly blame Pakistan's government but said that "bigger hands were involved."
Karzai said he would raise the issue as part of the investigation into the case.
The Pakistani government has rejected any connection with the attack, saying it was ready to help in the investigation.
