The price decrease is taking place in a situation where the American trade tariffs are weighing on consumer prices in China, which is already being pressed by a declining domestic demand.
China's consumer price index decreased by 0.1 per cent in April compared to the same month last year – which followed a similar decrease in March – and was in line with analysts' expectations.
The deflation pressure in China's economy risks becoming long-term due to US President Donald Trump's tariffs of 145 per cent on many Chinese goods.
The trade war could lead some companies to dump their products on the domestic market and thereby press the already low prices further.
