Nicolas Aguzin's comments, made in a speech to an online summit, come after Hong Kong Chief Executive Carrie Lam said she looked forward to the "early implementation" of the southbound Bond Connect, in a speech to the British Chamber of Commerce on June 17.

Aguzin did not provide a timeline for the launch of the programme in his speech.

The northbound leg of Bond Connect, launched in July 2017, expanded global investors' access to the Chinese onshore bond market, the world's second-largest.

Foreign holdings of Chinese bonds stood at a record 3.68 trillion yuan ($568.45 billion) at the end of May.

June data was not yet available on Friday from China Central Depository and Clearing Co and the Shanghai Clearing House.

The Bond Connect programme is operated by Bond Connect Company Ltd, a joint venture between HKEX and the China Foreign Exchange Trade System.
