European equity markets were set to open little changed on Tuesday as investors continued to assess the global outlook. Markets closely watched for developments in US-China trade talks in Spain, while looking ahead to an expected interest rate cut from the US Federal Reserve this week. The Bank of England will also set policy this week and is widely expected to keep rates unchanged. On the data front, investors will assess UK unemployment, Italian inflation, German economic sentiment and Eurozone industrial production. In premarket trade, Euro Stoxx 50 and Stoxx 600 futures were flat to slightly higher.
