China is attracting robust demand for its debut yuan-denominated green bonds in Canada, expanding its offshore debt footprint to finance sustainable projects as ties between the two nations warm.

The Ministry of Finance’s sovereign note sale, which kicked off Monday, has drawn over 40 billion yuan ($6 billion) of orders by midday in Hong Kong, according to people familiar with the matter. The three- and five-year notes, with the initial price guidance at yields of around 1.8% and 1.9%, respectively, is expected to price later Monday, they said, asking not to be identified discussing private matters.
