Teams recently salvaged the tour boat Phoenix, which sank off the coast of Phuket in July, according to a CCTV reporter.
Forty-seven Chinese lives were lost in the tragedy.
Professional teams from both China and Thailand will conduct a further investigation in order to confirm the exact cause leading to the tragedy.
Two tourist boats, named Phoenix and Serenata, carrying a total of 122 Chinese tourists, were overturned in rough seas on July 5. All 35 Chinese passengers on board Serenata were rescued while 47 out of 87 Chinese passengers on board Phoenix were killed.
