TOKYO: Benchmark Tokyo rubber futures extended declines into a third session on Friday, as Shanghai futures stayed in the doldrums amid concerns about weak global demand in top consumer China, brokers said.

The Tokyo Commodity Exchange rubber contract for April delivery finished 4.5 yen lower at 198.6 yen ($1.75) per kg. For the week, it fell 0.6 percent in its second straight weekly decline.

The most-active rubber contract on the Shanghai futures exchange for January delivery fell 75 yuan to finish at 13,855 yuan ($2,086) per tonne.—Reuters
