《元史·列传·卷九十五》
所以，曾派使修好。但为你们的边吏阻止而不得通行。我们曾抓获你们两个人，朕令有关官府对他们进行抚慰，托他们带信给你国王，但也复寂然无闻。
所获二人，敕有司慰抚，俾赍牒以还，遂复寂无所闻。
That is why I sent an envoy to improve relations. However, your border officials prevented them from moving forward. We once captured two of your men and I ordered the related authorities to look after them, asking them to relay my letter to your king. However, we have not heard back from you.
