Kim Yong Nam, North Korea's titular head of state and number two in the country's government, has met with a Syrian delegation in Pyongyang.
Confirmation of the talks, which were held over the past two days, came amid US and Israeli allegations of a nuclear connection between the two countries.
The Korean Central News Agency (KCNA), the country's official news outlet, said Kim Yong Nam had had "a friendly talk" with the Syrian delegation, which was led by Saaeed Eleia Dawood, director of the organisational department of Syria's Baath Arab Socialist Party.
'Secret suppliers'
KCNA said the Syrian official expressed satisfaction that the "friendly and cooperative ties" between the two countries "are growing stronger under the deep care of" Bashar Al-Assad, Syria's president and Kim Jong Il, the North Korean leader.
On Friday, the Syrian delegation held talks with Choe Tae Bok, a senior official of the North's ruling Workers' Party.
The delegation's trip to Pyongyang came amid allegations that the North may be providing nuclear assistance to Syria and against the background of an alleged Israeli airstrike on an undisclosed Syrian target on September 6.
Andrew Semmel, acting US deputy assistant secretary of state for nuclear nonproliferation policy, claimed last week that North Koreans were in Syria, and that Syria may have had contacts with "secret suppliers" to obtain nuclear equipment.
Pyongyang has angrily denied helping Syria, insisting it was sticking to an earlier pledge not to allow the transfer of nuclear materials.
In a landmark six-nation deal brokered in February, North Korea agreed to dismantle all its nuclear facilities and programmes in exchange for diplomatic concessions, energy and other aid.
