The deals, the first arms sales to Taiwan under the Trump administration, include sales of early warning radar surveillance systems, the joint stand-off weapon, torpedoes, missiles, electronic upgrades, and related parts.
US State Department spokeswoman Heather Nauert said the sales has yet to get the required congressional approval.
The US official emphasized that there was no change to the US' longstanding "One China" policy.
However, China's ambassador to Washington Cui Tiankai, speaking to reporters at an embassy reception in Washington on Thursday, said the arms sales to Taiwan along with recent US sanctions against some Chinese companies "will certainly undermine the mutual confidence between the two sides and runs counter to the spirit of the Mar-a-Lago summit."
The last US arms sales to Taiwan was announced in December 2015 under former president Barack Obama. The previous package was worth 1.83 billion US dollars and included two Navy frigates in addition to anti-tank missiles and amphibious attack vehicles.
