Positive signals from both the Chinese government and the White House about a trade agreement between the world's two largest economies are boosting the stock market mood globally.

The stock exchanges on Wall Street closed clearly upwards on Thursday and despite unexpectedly high inflation figures from the USA - which could contribute to slowing down potential cuts in the key interest rate by the USA's central bank Federal Reserve (Fed) - it is green on the US stock exchange after a few hours of trading.
