The party "may block NATO supply routes in Punjab and Balochistan as supply is being carried out via Chaman border," Imran said.
"National and Khyber-Pakhtunkhwa assemblies had unanimously passed resolutions terming drone strikes a blatant violation of international law and Pakistan's sovereignty," he said.
He said the supply route would remain closed until the US stopped drone attacks.
Claiming that the US was creating hurdles in the peace process, he said "the so-called ally" did not want to bring peace to the region.
Meanwhile, his party today welcomed the news of the US military halting ground cargo shipments from Afghanistan via Pakistan because of the its protests.
The party's Central Information Secretary said, "This was a tactical success for the Party's protest. However the strategic success would come when the US committed to stopping drone attacks on Pakistan."
In Washington, Pentagon spokesman Mark Wright said, "We are aware protests have affected one of the primary commercial transit routes between Pakistan and Afghanistan."
"We have voluntarily halted US shipments of retrograde cargo...from Torkham Gate through Karachi to ensure the safety of the drivers contracted to move our equipment."
