Western companies are showing serious interest in buying into Motor Sich, the aircraft motor factory, in 2020, outgoing acting US Ambassador William B. Taylor Jr. told a group of journalists Thursday in a farewell interview. “They are looking for investors,” he said of Motor Sich which is an acquisition target for two Chinese companies. “There are a couple of investors — American and others — who are very interested. They’re doing some due diligence, checking balance sheets, visiting the plant, talking to the owners. They’re doing some serious evaluation.”
