The bar chart below compares export earnings of 5 types of products between 2015 and 2016, and the table illustrates the increasing or decreasing proportion on these categories.

In summary, the most export earning was obtained by petroleum industries in both 2015 and 2016, and the value of textiles ranked last in the same time. However, a highest increasing percentage could be seen on the lowest valuable goods during this period.

Looking at the bar chart, in both 2015 and 2016, the highest value of these 5 categories was petroleum products, with around 61 billion dollars in 2015, 62 billion dollars in 2016, respectively. And the second highest one was engineered goods, approximately 57 billion dollars in the first year, and more than 60 billion dollars in the next year. The textiles manufacturer earned the least in the 2 years, less than half of the 2 top export earning factories.

However, although it earned the least, a highest rise could be found on the percentage of the value of textiles during this 2 years, with 15.24%, about 5 times of the most earning products(3%), and double times of the second most earning goods(8.5%). Besides, the value of all the export categories were increasing, apart from the agriculture products, a 0.81% decline could be seen on that.
