Share prices in Japan have lost all of their gains made so far this year as the concerns over the Chinese economy continue to have a dramatic impact.

The Nikkei index fell below 17,450.77 points on Tuesday, where it started the year, before closing at 17,427.08.

Financial analysts said Japanese investors were put off by yet another set of gloomy economic data from China. Chinese imports fell 14.3% and exports were down 6% in August.

Despite the weaker figures, the Shanghai Composite index rose 1.89% to 3,138.64 points. And the Hong Kong Hang Send index was up 1.59% at 20,913.18.
