Foreign Ministry spokeswoman Jiang Yu says Premier Wen's visit will reciprocate a visit to China in March by North Korean leader Kim Jong Il.
Jiang says during this visit, China will review its relations with North Korea and "map out the development plan for the future of bilateral relations."
She says the visit, which begins Sunday and ends Tuesday, will have concrete results, but gave no details.
The spokeswoman says the two sides will sign a series of cooperation agreements, dealing with trade, tourism and education.
She said China has been helping North Korea "within its capacity."
