China has stepped up gray-zone warfare against Taiwan, aiming to make the areas around the democratic island "saturated" with balloons, drones and civilian boats, a Taiwan Defense Ministry report said on Thursday.
Taiwan, whose government rejects Beijing's sovereignty claims, has complained in recent years that China has been using so-called gray-zone warfare, which wields irregular tactics to exhaust a foe without resorting to open combat.
In a report sent to parliament, the ministry said Beijing has launched "multifront saturated gray-zone" tactics to harass Taiwan, including increased patrols of ships and planes.
