Trade with China’s Muslim-dominated province of Xinjiang hovered around $1.6 billion during the first quarter of 2015, recording an increase of nearly 89.4% compared with the similar period in 2014, IRNA reported, citing the latest statistics released by Xinjiang customs administration. “Despite a 38.2% decrease in the province’s overall trade during the period, trade with Iran is showing a drastic increase,” the report added. Xinjiang Uyghur is an autonomous region of China in the northwest of the country. The province borders with Mongolia, Kyrgyzstan, Tajikistan, Afghanistan, Pakistan and India. It has abundant oil reserves and is China’s largest natural gas-producing region. The province recorded a gross production of 10% during 2014, nearly 3% higher than China’s national gross production in the same year.
