China's Odd Corn Import Diversification

In 2012, Chinese officials were alarmed to discover that 99% of the country's corn imports came from the United States. They immediately rushed out to sign up Ukraine and Argentina as corn suppliers. Later, they signed up Bulgaria.

An article reviewing China's 2014 corn imports concludes that China did indeed diversify its corn imports. Corn imports were down 20% during 2014, and all of the decrease reflected reduced imports from the United States due to rejections over the MIR162 issue. Imports from Ukraine, Thailand, Laos, and Myanmar increased. The Guoji Shangbao (Global Business News) article announced that the U.S. share of China's corn imports fell to 40%, "comparable to the proportion from Ukraine."

This is a curious strategy for a country obsessed with "food security." The largest and most reliable corn supplier in the world is knocking on your door, offering to sell you as much corn as you want. So you rush out to sign agreements with regimes with a history of political instability and debt crisis. You make a multi-year commitment to a country that has an actual war in its territory threatening its crops and make it your featured new corn-supplier.
 
So maybe China was worried that the United States would use its monopoly position as a corn-supplier to gouge Chinese buyers. But now the Chinese government is using its monopoly position to force its corn buyers to pay twice as much for corn as their competitors in other countries, so maybe Chinese officials are not all that concerned about price-gouging.
 
In reality, a monopoly over a particular commodity is hard to establish because there are substitutes. Chinese officials may not have realized that there are substitutes for corn. Imports of distillers dried grains, sorghum, and barley have poured in...and the United States was the main supplier. China managed to break the U.S. monopoly of its corn imports by brute force, but instead the U.S. supplied China with 11.2 mmt of sorghum and DDGS.

So, what did China accomplish by banning U.S. corn for a year? The Ministry of Agriculture has approved the MIR162 corn variety, so this type of corn will enter the Chinese market after all. They equalized the shares of U.S. and Ukrainian corn imports last year, but created a big market for feed-quality sorghum, barley, and DDGS.

I'm curious if you have these graphs with the 2015 import data in them as well? Or is there a way that I can contact you to find out where these data sets come from?

China's Vanishing Soybean Self-Sufficiency Rhetoric

Chinese propagandists appear to have given up on soybean self-sufficiency now that China has gained the upper hand over the U.S. on the soybean trade war front. The barrage of Chinese articles about finding soymeal substitutes, low protein animal diets, corn-soy intercropping, etc. has quietly faded from Chinese media. China's plan to bolster soybean self-sufficiency actually failed, but Brazil's bottomless soybean supplies nevertheless enabled China to snub U.S. soybean producers during last year's trade war. Xi Jinping now is free to make offers of soybean purchases to President Trump in trade negotiations without appearing to do so from a weak position. Mission accomplished, but not in the way Chinese strategists planned. Back in 2019--at the height of the first U.S.-China trade war--China's "Number 1 Document" announced a "soybean revitalization plan" to increase self-sufficiency in soybeans. Soybeans were pronounced to have strategic significanc...

Xi Jinping's Doctoral Thesis

Xi Jinping is the vice president and presumed next president of China but little is known about him. In this post the dimsums blog offers its contribution to the genre of Xi Jinping-ology by conveying Xi's decade-old views on agricultural markets. Ten years ago Xi Jinping wrote a thesis, "Tentative Study of Agricultural Marketization" (中国农村市场化研究) for a Doctor of Law degree at Tsinghua University in Beijing, a top breeding-ground for Chinese officials. The dimsums blogger has spent several hours poring over the 200-plus page tome to see what it reveals about Dr. Xi. The thesis is remarkably close to what China has been doing lately in agricultural policy, suggesting that Xi (or the person who actually wrote the thesis) has a major say in policy or is at least in agreement with what's being done. There is nothing adventurous, controversial (or insightful) in the thesis. It seems to be the work of a wonkish technocrat who is not prone to talk out of turn or wander from...

Divergence in U.S. & Chinese egg prices

High egg prices are a hot topic in the United States. China, in contrast, has a glut of eggs and depressed prices.  The March 14, 2025 USDA Agricultural Marketing Service weekly eggs market overview reported that U.S. egg prices continued declining during the second week of March as the supply situation improved. No significant highly pathogenic avian influenza (HPAI) outbreaks have occurred in March and U.S. egg demand is relatively light. The average U.S. wholesale price for Grade A large white eggs was $4.15 per dozen, down sharply from their February peak.  Until 2021, Chinese and U.S. wholesale egg prices had been roughly equal at about $1-to-$2 per dozen with no trend. U.S. prices fluctuated more than Chinese prices, so the U.S. price was sometimes higher, sometimes lower than the Chinese price after converting them to dollars per dozen.  Chinese prices converted using monthly exchange rate and assuming 0.6 kg per dozen.
