The issues were discussed during a meeting between visiting Iranian Deputy Minister of Roads and Urban Development Mohammad Saeed Izadi and South Korean Vice Minister for Land, Infrastructure and Transport Kim Kyung-hwan in Seoul on Wednesday.
In the meeting, Kim pointed to the agreements inked recently between the two ministries and called for their implementation at the earliest.
Referring to the South Korea's interest in taking part in road construction and urban development projects in Iran, Kim urged the Iranian government to support South Korean companies.
He pointed to the historic visit by South Korean President Park Geun-hye to Tehran in May and said Seoul and Tehran have inked five cooperation documents in road and urban developments.
In May, Iran and South Korea signed 19 cooperation documents in Tehran, pledging to increase annual trade figures threefold from the current $6 billion to $18 billion.
"We discussed tourism, direct Seoul-Tehran flights and Korean investment in Iranian tourism infrastructure, including building hotels," President Hassan Rouhani said in a joint press conference with his South Korean counterpart Park Geun-Hye.
"We should increase bilateral trade, which has dropped in recent years, to $18 billion in the first phase, and then to $30 billion in the mid-term," Rouhani added.
Iran and South Korea have the potential to expand relations in ICT, nanotechnology, environment protection, industry, and agriculture, he explained.
The Korean president said, "We will expand relations in energy projects and infrastructure, as well as in oil, gas, car, health, and high-tech industries."
