China initially sought to acquire high-tech weapons that Israel developed by copying U.S. technologies....
...In 2005, the United States obliged Israel to hold consultations with it before exporting advanced weaponry to third countries, making Israel effectively unable to supply such technologies. But even after that, it cannot be ruled out that a large quantity of gray-zone products, such as electronic and precision machinery, has been exported from Israel to China. Last year, the two countries' trading volume reached about 5 billion dollars, a twofold increase in five years.
Doesn't seem like sound investment to me. Time to pull the plug. Especially since there are very few countries ahead of Israel in EXPORTING arms. I think the list is US, Russia, France, ISRAEL, Britain.
