Google suspends Chinese shopping app over security issues.

Google has suspended the Chinese e-commerce app Pinduoduo from its app store due to security concerns after malware was found in versions of the app from other sources. The suspension comes amid heightened tensions between the US and China over Chinese-owned apps, with some US lawmakers alleging that they could be a national security threat. Pinduoduo is a popular app in China that offers discounts if users team up to buy multiples of an item. Google has warned users to uninstall any Pinduoduo app not downloaded from its own Play store.
