The 15-year loans, of €9.3 billion and 9.8 billion yuan ($1.48 billion), were signed by the two Chinese financial institutions in late April.
The latest disbursement followed the first chunk of €450 million ($507 million) Yamal received in late July.
Before receiving the financing from the Chinese banks, the project's future had been jeopardised by Russia's lack of access to Western capital markets after Europe, the US and a group of other countries imposed sanctions on Moscow for its role in the Ukraine crisis.
