China’s Xiaomi, Huawei Technologies, Oppo and Vivo are reportedly joining forces to create a platform for developers outside China to upload apps onto all of their app stores simultaneously.

According to Reuters, the four companies are working on what is known as the Global Developer Service Alliance (GDSA). The platform aims to make it easier for developers of games, music, movies and other apps to market their apps in overseas markets, according to the report.

According to the description of the GDSA on its website:

The Global Developer Service Alliance (GDSA) is committed to providing one-stop services including content distribution, development support, marketing operation, brand promotion and traffic monetization to global developers . These services help developers improve their brand awareness, and obtain a large number of high-quality users and traffic monetization. Our services have covered nine countries and regions such as India, Indonesia, Russia and Malaysia. GDSA is looking forward to working with extraordinary developers to move forward together and achieve win-win cooperation.

The GDSA could launch as soon as next month, although it is not clear how that will be affected by the recent coronavirus outbreak.

All four companies declined to comment for this story.

Google's services are banned in China. However, the company earned about $8.8 billion globally from the Play store in 2019. Google also sells content such as movies, books and apps on the Play store and collects a 30% commission.

Together the four companies made up 40.1% of global handset shipments in the fourth quarter of 2019, according to the consultancy IDC. While Oppo, Vivo and Xiaomi have full access to Google services in international markets, Huawei lost access for new devices last year after the United States barred American suppliers from selling goods and service to it, citing national security.

Xiaomi has a strong user base in India. Vivo and Oppo dominate the Southeast Asia region, while Huawei is very popular in Europe. The alliance could add pressure to Google and build more negotiation power against the Android provider.
