Shares down as Huawei arrest sparks fresh trade war concerns
Asian stock markets have fallen sharply amid fears the US-China trade war could escalate after the arrest of Meng Wanzhou.
Financial markets are enduring further turmoil after the arrest of a Chinese Huawei executive on behalf of the US exacerbated fears over the countries' trade war.
Ms Meng is also the daughter of Ren Zhengfei, the founder of the communications technology company - China's largest technology firm.
The arrest is believed to be related to alleged violations of US sanctions against Iran though there has been no official statement from Washington.
