Tensions over Taiwan have surged in recent weeks. On September 19, US Undersecretary of State Keith Krach visited Taiwan, and Beijing responded by launching military exercises and sending 16 fighter jets and two bombers careening through Taiwan's airspace.
Krach was in fact the second notable US visitor to the island in just two months. In both cases, Beijing responded with a show of force. The US is reportedly also considering the sale of precision-guided missiles to Taiwan. China has responded with threats of sanctions against US companies.
