Huawei CFO Sabrina Meng Wanzhou out on bail - but what is the case about?

After more than a week in custody, Meng Wanzhou, the chief financial officer of Chinese tech giant Huawei, was released on bail by a Canadian court on Tuesday. But as lawyers prepare for a possible future trial, court papers have shed new light on how the world’s largest telecommunications equipment maker has been the subject of an investigation by US authorities for years.

Meng, 46, was arrested at the request of the US government on December 1 at Vancouver airport while she was transiting to Mexico. Her detention came on the same day that Chinese President Xi Jinping sat down for dinner with his US counterpart Donald Trump in Argentina to agree a truce in their trade war.
