TOKYO: Tokyo Commodity Exchange (TOCOM) futures plunged 4% on Friday, extending losses into a sixth straight session, as investors worried about weaker global demand from escalating US-Sino trade war, leading to the biggest weekly loss since March 2018.

* The benchmark TOCOM rubber contract for January delivery  finished 6.8 yen, or 4.0%, lower at 168.5 yen ($1.58) per kg, after touching the lowest since Dec. 26, 2018 of 166.9 yen earlier in the session.

* For the week, it booked an 8.1% slide, marking a second consecutive weekly loss.

* US President Donald Trump said he plans to impose a 10% tariff on $300 billion of Chinese imports from Sept. 1 and could raise tariffs further if Chinese President Xi Jinping fails to move more quickly to strike a trade deal.
