BEIJING, Aug 10 (Reuters) - A Chinese court is expected to rule as early as Wednesday in the case of detained Canadian Michael Spavor, according to a Canadian source directly familiar with the matter. Spavor, a businessman, was charged with espionage in June last year along with fellow Canadian Michael Kovrig, at a time when relations between the two countries are at a very low level following Canada"s arrest of a Huawei executive in late 2018.
