evidence: The previous chapters centred around maritime hybrid warfare and hybrid conflicts in or near the Strait of Hormuz, the Bab el-Mandeb, the Viro Strait, the Taiwan Strait, and the Kerch Strait. This chapter focuses on the Straits of Malacca and Singapore that together with the Straits of Sunda and Lombok serve as the main gateways to the South China Sea. The Straits of Malacca and Singapore have not been a theatre of hybrid warfare or hybrid conflict, but similarly to the Åland Strait this waterway appears particularly vulnerable to hybrid threats.
