Factory data released by Beijing has shown signs that the Chinese government’s push to restart the economy has seen some early results. The National Bureau of Statistics found that China’s industrial production increased by 3.9% in April, its first rise since the beginning of the year. The increase beat even analysts’ projected rise of 1.5%.

Following the figures’ release, early Friday trading saw European stocks buoyed. France’s CAC 40 rose by 1%, Germany’s DAX by 1.3%, and London’s FTSE 100 by 1.3%. The pan-European STOXX 600 index saw an increase of 1.2%.

US futures also showed signs of improving, with the S&P 500 and Dow Jones Industrial Average futures rising by more than 0.3% each, and Nasdaq by 0.5%.

These positive signs were later reversed, however, as it emerged that the US government intends to block microchip shipments to Chinese telecommunications giant Huawei, a move likely to escalate tensions between the two countries. As a consequence, the S&P 500 and the DOW slipped by 1.1%, with Nasdaq ending 1.4% in the red.

China’s own stock indexes saw little change, with the Shanghai composite finishing 0.07% down. Elsewhere in Asia, South Korea’s Kospi rose by 0.12% and Japan’s Nikkei by 0.62%, apparently undisturbed by China’s industrial growth or trade tensions.
