The U.S. trade ban has affected Huawei's mobile business outside China in different ways including the inability to make use of Google apps and services aka Google Play Services. This is the reason all of the new Huawei phones including the Mate 30 series that became official after the ban lack Google apps. It has been working on an alternative since then and has now released Huawei Mobile Services (HMS) in China.
Huawei Mobile Services is basically a collection of apps and services that are supposed to replace Google's offerings. Some of the included apps are said to be Huawei AppGallery, Huawei Browser, Huawei Mobile Cloud, Huawei Themes, Huawei Music, Huawei Video, Huawei Reader, and Huawei Assistant among others. These are essentially replacements for Google Photos, Google Chrome, Google Drive, YouTube Music, YouTube, Google Play Books, and Google Assistant.
There are reported to be about 45,000 apps available via HMS which is undoubtedly a very low count as compared to over 3 million apps on the Google Play Store. But Huawei had previously announced that it is committed to reducing the gap as much as possible. It has even set up a $1 billion reward fund to encourage app developers so that they can create or port their apps to the HMS ecosystem.
It is worth noting that Huawei also has its own operating system named HarmonyOS. It is currently available on smart TVs and is meant for Internet of Things devices but with corrects apps/services ecosystem, it can also expand to smartphones and tablets in the future.
