We present CrossSum, a large-scale dataset |

comprising 1.70 million cross-lingual article summary samples in 1500+ language-pairs |

constituting 45 languages. We use the multilingual XL-Sum dataset and align identical |

articles written in different languages via crosslingual retrieval using a language-agnostic |

representation model. |
