Lei Sheng became the first Chinese man to win the men's Olympic foil gold, overcoming a brave bid from Egypt's Alaaeldin Abouelkassem in the first final of the event since 1900 not to feature a European.

"I did not expect this, I was not thinking about this," Lei, who prevailed 15-13, said through an interpreter with his pristine medal around his neck.

Lei forged an early 6-2 lead but Abouelkassem hit back. At one point he led 13-11 but Lei, who placed eighth at the 2008 Games, regained his composure to triumph.

"I was surprised by my own performance," the emotionally overwhelmed Chinese fencer said.

"I did not think about winning the gold, just to fence the match one by one. But I was very confident of myself," he said.

He said his confidence did not falter when falling behind 11-9, knowing he still had the chance to win.

"It did not disturb me, I told myself at that moment that so long as the match is not over, I have the chance," he said.

The 28-year-old, ranked ninth in the world, had beaten former world champion Andrea Baldini in the semifinal round.

Abouelkassem, who beat two former world champions in London, was equally amazed to be standing on the podium, the first fencer from Africa to do so.

Choi Byung-chul of South Korea took bronze.

Much was expected of Italy's men's foil team but they failed to match their female counterparts who enjoyed a clean sweep of the medals on the opening day.

Baldini's path to the 2012 Games was longer than most, having tested positive for a banned diuretic before the Beijing Olympic Games.

He protested his innocence and fencing's world governing body FIE noted an Italian prosecutor deemed an unidentified third party was responsible for his unknowingly ingesting a banned substance. Sanctioned with ineligibility for six months, he returned to win the 2009 world title.

"Yes, every match was very physical. I felt a lot the stress, not just from today but the last four years to think about being here at the Olympic Games. Yeah, I am tired," he said through a translator, adding he will try for the 2016 games in Rio de Janeiro.

Abouelkassem, born to an Algerian mother and Egyptian father, said he feared most of all facing Baldini in the bronze medal match, using that motivation to beat Choi 15-12 in the semifinals and head for the gold medal match against Lei.

"I still cannot believe it. I had to take 15 minutes to realize what I did. I am very happy," the 21-year-old Egyptian said of his silver medal.
