The Confederation of African Football (CAF) had already said the January 10-31 tournament would proceed despite the attack in Cabinda, in which the driver was killed and nine others were injured.
CAF president Issa Hayatou will now meet Angola's prime minister Paulo Kassoma in Luanda on Saturday.
"They will meet to take decisions to guarantee the smooth running of the competition," said a CAF statement released early on Saturday.
Gunmen opened fire as the team were entering Angola from neigbouring Congo and the Togo team have yet to make a decision on whether they would participate in the tournament.
A group of senior African football officials are travelling with an Angolan government delegation to investigate the attack, responsibility for which has been claimed by a separatist movement in the oil-rich enclave.
The CAF condemned the attack on the Togo team.
"The Confederation of African Football is terribly saddened by this event and express its total support as well as sympathy to the entire Togolese delegation," the statement added.
