instruction:
This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning). 
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.

Passage: In 2007, Kuwait supplied China with  of oil per day, accounting for 2.6% of Chinas total crude oil imports.  Saudi Arabia was Chinas top supplier with its shipments jumping 69.8 percent to 3.84 million tons (939,000 bbl/d), followed by Angola with 2.06 million tons (503,000 bbl/d), down 27.1 percent. Iran became third, with imports from the country shrinking 35.3 percent to 1.18 million tons (289,000 bbl/d). China is the worlds second-biggest oil consumer after the US. Abdullatif Al-Houti, Managing Director of International Marketing at state-run Kuwait Petroleum Corporation (KPC), told KUNA in October that Kuwait is on course for its China-bound crude oil export target of  by 2015, but success will heavily depend on the Sino-Kuwaiti refinery project. The two countries have been in talks for the planned  refinery in Chinas southern Guangdong Province. The complex is expected to be on-stream by 2020.
answer:
How many less tons of crude oil than Angola does Iran supply China?
