bargaining chip

"China holds a bargaining chip, not a financial weapon."

“Regardless of this or any letter, we hold firm that basic needs of our nation’s children must not become bargaining chips.”

Many see these tariffs as Trump's bargaining chip in trade negotiations with India.

Trump sees tariffs as a way of protecting the US economy from unfair competition and as a bargaining chip for getting better trading terms for America.

She has also refused to use oil as a bargaining chip to fight back against US tariffs - breaking away from the position held by most other provincial leaders.
