In a daily press briefing by the State Department, Deputy Spokesperson Mark Toner on Thursday said: "Let's give this gentleman a chance to get up to speed, but we certainly congratulate him on the appointment and welcome his -- the transition to a new chief of army staff."
Toner said the US maintains close cooperation with Pakistan on counter-terrorism operations.
"With respect to our counter-terrorism cooperation with Pakistan, that's ongoing. We work with them quite closely," he said.
The deputy spokesperson further added: "They're aware of some of our concerns, which include a safe haven for some terrorist groups that are active in the region."
Gen Bajwa became the 16th army chief of Pakistan on November 29.
