By Reuters Staff (Updates with SWIFT comments) SHANGHAI, Feb 4 (Reuters) - SWIFT, the global system for financial messaging and cross-border payments, has set up a joint venture with the Chinese central bank’s digital currency research institute and clearing centre, a move some see as a sign that China wants to explore global use of its planned digital yuan. Other shareholders of the Beijing-based venture include China’s Cross-border Interbank Payment System (CIPS) and the Payment & Clearing Association of China, both supervised by the People’s Bank of China (PBOC), according to public information. The new entity, called Finance Gateway Information Services Co, was established in Beijing on Jan. 16, and its business scope includes information system integration, data processing and technological consultancy, according to the website of the National Enterprise Credit Information Public System.
