China exports to US rise even as Trump tariffs take effect
China can artificially lower or raise the price of the products sold by Chinese companies. The model used by China is not capitalism but something closer to the National Socialist model where private entities are tolerated but so heavily regulated that the government has de facto control over everything including price.
Here China can artificially lower price to continue to undercut other producers and keep importing products to Ameican even with tariffs. China will consider this a win, but the rational businessman would look at the same issue and realize that he cannot make up a per item loss in volume of sales. In essence, he would find it silly to believe that if he were losing a $1 per product he could make this up by selling twice as many products. The businessman will see this will only double his losses. The Chinese cannot see this in the same way and believe that it is more important to sell even it at a loss.
By doing so, they will only accelerate their demise, and the erode the nation's treasure more quickly.
The other thing likely happening is some market flooding with pre tariff Chinese goods. But this is a short-term solution which will have no long-term effect.
"The figures suggest that the administration's aggressive efforts to reverse the trade deficit with China through tariffs and other measures are not yet having the intended effect, despite some administration claims that Beijing is on the ropes.
Some economists believe the current data shows that China is flooding the market now to get its exports out before the tariffs rise in 2019, and therefore the current export levels cannot be sustained."
The first paragraph is silly, the second is likely.
China will engineer the trade to appear as if Trump is losing while he will be achieving his goals.
