Admiral Samuel Paparo, the head of United States forces for the Indo-Pacific, warned Senate lawmakers about the implications of a war with China over the island of Taiwan.

Should China try to take Taiwan militarily, it would result in a 25% Gross Domestic Product (GDP) contraction in Asia and it would have a “knock on effect of 10 to 12% GDP reduction in the United States of America,” Paparo told the Senate Armed Services Committee on Thursday.
