The Biden administration has informed Congress of a proposed $750 million weapons sale to Taiwan in a move likely to further inflame tensions with Beijing.

The administration gave notice about the intended sale on Wednesday, according to a State Department spokesperson, two congressional sources, and a notification from the Defense Security Cooperation Agency. The deal includes 40 M109A6 Medium Self-Propelled Howitzer Systems and related equipment.

"If concluded, this proposed sale will contribute to the modernization of Taiwan's howitzer fleet, strengthening its self-defense capabilities to meet current and future threats," the spokesperson said.

One of the congressional sources told CNN that Senate Foreign Relations Chairman Robert Menendez had already cleared the sale as part of the informal review process -- a common practice in which the House and Senate Foreign Relations Committees get a heads-up on planned sales, allowing committee leadership to raise concerns, give their input or place holds.
