Pacquiao also said his match against American Brandon Rios in the Chinese territory of Macau next month would be “a good window” to promote boxing in China, and that he felt honored to take part in the landmark bout.
“This training camp, I believe, is one of the longest preparations in my boxing career. I trained early because I want to prove that I can still fight in the top (tier) of boxing,” he told reporters late Wednesday in his hometown of General Santos in the southern Philippines.
“This time my preparation is more serious, more focused. My mind is like when I was 20 years old.”
A former champion in an unprecedented eight weight divisions, Pacquiao, who turns 35 in December, is seeking to come back from two consecutive defeats which have led supporters to question if he should hang up his gloves.
He lost a controversial split decision to American Timothy Bradley in June last year, then suffered a sixth-round knockout to Mexican arch rival Juan Manuel Marquez six months later.
Pacquiao said he had come to terms with his shock defeat to Marquez, reasoning that losing was inevitable during a long sporting career.
“I don’t think I had a mistake in that fight. If you look back… I had 100 percent conditioning, aggressiveness. That (defeat) is part of boxing. I accept 100 percent what happened in the last fight,” he said.
While he had done light training earlier, Pacquiao formally opened his training camp in General Santos last month.
His training to meet Rios, for the vacant World Boxing Organization (WBO) welterweight title, has largely been behind closed doors.
This is in contrast to many of his previous training camps, where journalists, celebrities and other guests have dropped by to pose with the boxer.
Critics have previously questioned whether Pacquiao’s diminishing prowess in the ring was because he had become distracted by his many other endeavors.
His boxing fame helped him to launch a successful political career in the Philippines, and he is now a second-term congressman with ambitions of eventually becoming president.
Pacquiao, who through the peak of his career fought almost exclusively in the United States, appeared excited at the prospect of raising the sport’s profile in the world’s most populous nation.
