Conferences from an Unnamed Organizer in China

I am seeing more spam for conferences that do not disclose who is behind the conference -- no names (fictitious or otherwise), no addresses, nothing but a one-off conference name and website.The separate conference webpages, some of which claim to have American universities as co-sponsors, contain the same Beijing mobile telephone number: +86-13618615451. The email originated from a Chinese server, and the email addresses on the individual conference websites are for accounts from Chinese email service providers.

Conference names with the Beijing number include AICAE2019 (zai Wuhan), CEME2018 (Shanghai), CIMNS2018 (Wuhan), ECAE2018 (Wuhan), EMCAR2019 (Beijing), ICEPECA2019 (Wuhan), ICEPESE2018 (Xiamen), and SSEMR2019 (Hangzhou).

Another common feature is a promise of publication in a DEStech journal (for "excellent" papers). The publisher has been characterized as predatory.
