The trade war between the United States and other major economies escalated on Friday after Washington and Beijing launched punitive import tariffs on $34bn (£25.7bn) worth of each other's goods. "We are un-willing to fight, but in order to safeguard the interests of the country and the people, we have to fight if necessary". China's imports of American oil have surged over the past year and a half, climbing from $100 million per month at the beginning of 2017 to almost $1 billion per month.

"Companies don't know how big this may get, or how it will end".
It is not often that the niche world of commodities trading enters the public conversation, but on Friday China's social media was rooting for a ship carrying soybeans from the United States to beat the deadline before Chinese tariffs kicked in.
