Iran has taken international media on a tour of partially completed natural gas facilities and other elements of its energy sector to display its capabilities, just days after the easing of sanctions in an effort to entice foreign investors.

Tehran could use outside expertise to further develop the sector, including a massive natural gas field it shares with the nearby Arab nation of Qatar.

The tour of South Pars gas field Wednesday was a way to show investors the energy sector's potential.

It came just three days after Iran began implementing a November deal with world powers under which Tehran capped its uranium enrichment in return for the easing of some Western sanctions.

In December, President Hassan Rouhani said Iran intends to significantly increase production from the field by 2017.
