China says it opposes "politicising" normal business exchanges, after Germany blocked the sale of a gas turbine unit to a Chinese firm over apparent security concerns. MAN Energy Solutions, a subsidiary of Volkswagen group, had been due to sell the unit to Chinese group GHGT and its offshoot Guanghan Gas Turbine. But Germany's economy ministry said Wednesday that Chancellor Olaf Scholz's cabinet had prohibited the move, declining to provide further details owing to security concerns and the company's operational secrets.
