In coking coal, if China doubled the most it has ever bought from the United States in a month, it would imply annual imports of around 20 million tonnes, worth about $3 billion, and equivalent to around 40% of US total coking coal shipments.
Again, this may be possible, but would result in a disruption of flows as other Asian coking coal importers such as Japan, South Korea and India would have to switch suppliers and re-negotiate deals.
Overall, there are two things that become clear from the so-called Phase 1 trade deal, firstly the target for energy imports is probably unrealistically high, and secondly, if China does try to meet the target it will prove disruptive for markets.
