Iranian Foreign Ministry spokesperson Nasser Kanaani revealed on Monday that a North Korean delegation attended a Tehran expo last week, engaging in discussions on bilateral trade with both Iranian government officials and the private sector.

The 6th Exhibition on Export Potential of the Islamic Republic of Iran, dubbed ‘IRANEXPO 2024,’ is being held in Tehran from 27 April to 1 May.

North Korea's official media reported last week that a delegation led by the cabinet minister for international trade was visiting Iran, marking a rare public acknowledgment of ties between the two countries with presumed secret military cooperation.

Despite long-standing suspicions of collaboration between North Korea and Iran on ballistic missile programs, Kanaani rejected such claims, denouncing certain media outlets for "biased speculations by publishing untrue and baseless news".

The minister for external economic relations, Yun Jong Ho, led the delegation's visit to Iran, according to North Korea's KCNA news agency. Yun, who has previously focused on Syria relations, has been actively involved in bolstering ties with Russia, leading a delegation to Moscow earlier this month.

In the face of denials, suspicions persist regarding ballistic missile collaborations between Iran, North Korea, and Russia, with reports indicating Iran's supply of ballistic missiles to Russia for its invasion of Ukraine.
