Samsung Electronics said on Thursday its chairman met with the heads of Meta, Qualcomm, and Amazon this week to discuss cooperation and that topics included artificial intelligence, cloud services, and chips.

Meta’s Mark Zuckerberg invited Jay Y. Lee to his home on Tuesday and their discussions spanned AI as well as virtual and augmented reality, Samsung said in a statement. Lee is on a two-week visit to the United States.

Samsung has lost ground compared to competitors in chips, especially high-end memory for AI, and its newly appointed head of its semiconductor division has called on staff to pull together to overcome a raft of challenges.

Amazon is a key Samsung client for chips and the two firms also work together in various fields such as TV, mobile and content.

Samsung’s high-end smartphones use Qualcomm’s Snapdragon mobile processors, and the companies have recently expanded their partnership to AI-enabled PCs.

Meta is also a Samsung chip client and it has worked with Samsung on the South Korean firm’s Gear VR headset and foldable smartphones.
