China will replenish 35 billion yuan (about US$4.9 billion) to this year's third batch of ultra-long special treasury bonds on August 9, the Ministry of Finance said Friday.

The bonds will be issued at the Beijing Stock Exchange with a term of 50 years and an interest rate matching that of the previous issuance of the third batch of such bonds at 2.53%.

This move will supplement the country's 50-year ultra-long special treasury bonds, also worth 35 billion yuan, initiated in June this year.

Ultra-long special treasury bonds typically refer to those with a tenor of more than 10 years.
