The Pentagon has discovered that Chinese companies are aiding the Iran-backed Houthi rebels in Yemen in targeting American ships, as the fallout from the US-China trade war continues. A Chinese satellite company linked to Beijing's military is reportedly providing the rebels with imagery to target US warships and international vessels in the Red Sea. The discovery comes as the trade war between the US and China deepens, with President Trump imposing new tariffs on imports from China. The attacks by the Houthi rebels have caused major disruptions to global trade and shipping traffic in the Red Sea has dropped by 75%.
