Lebanon participated in the country's first ever football competition in the history as host, but began disappointingly, losing 0–4 to Iran. Lebanon sought to reinvigorate the team against Iraq and Thailand, but all ended up in just draws, and Lebanon finished bottom in the group, the first host nation since Qatar 1988 to not progress from the group stage. Iran and Iraq managed to survive in the group A with seven and four points respectively, and Thailand took the third, but did not progress due to inferior points, having won no match in their group. Group B saw South Korea failed to achieve a top two finish, falling behind group winner China and Kuwait, but qualified as the best third place team, with the team's only win was against Indonesia. Indonesia was the only team to not score a single goal in the tournament, being beaten by South Korea and China, and a goalless draw with Kuwait. Group C witnessed Uzbekistan to become the worst-performed team in the tournament, being heavily beaten 1–8 by Japan and 0–5 by defending champions Saudi Arabia. The Japanese scrambled to top the group with a famous 4–1 win over the Saudis, though Saudi Arabia would go on to progress together after an unpromising group stage performance. Qatar, another participant in the group, finished in third and progressed thanked for one point ahead of Thailand, having drawn in all three matches. The quarter-finals saw Iran lost 1–2 to South Korea by a golden goal of
Lee Dong-gook, and the same happened in Saudi Arabia's victory over Kuwait, also by a golden goal of
Nawaf Al-Temyat. China and Japan easily passed through their Arab rivals Qatar and Iraq, with 3–1 and 4–1 wins respectively, to set up an entirely East Asian affair in the semi-finals, with Saudi Arabia being the only non-East Asian team to be here. The first semi-finals saw Saudi Arabia sealed the victory over the South Koreans, with two goals by
Talal Al-Meshal at 76' and 80' meant
Lee Dong-gook's late equalizer was too little, too late. Japan beat China in a thriller in Beirut, 3–2, to once again face the Saudis in the final. In the third place match, South Korea won bronze with a 1–0 win over China. The final in Beirut was filled with majority of Saudi supporters, and was seen as the rematch of the 1992 final and earlier group stage encounter.
Hamzah Idris had a chance to take the Saudis ahead of Japan at 10', but he missed the opportunity. Eventually, the missing penalty was what the Saudis regretted the most, because
Shigeyoshi Mochizuki, who had accidentally given the Saudis the failed opportunity on the penalty earlier, became the hero of Japan with a goal in 30'. Saudi attempt proved to be fruitless, and Japan won the game by just one goal margin, to conquer its second Asian trophy, repeating Japan's victory over Saudi Arabia eight years ago. Subsequently, Japan, the winner, automatically qualified for the
2004 AFC Asian Cup. ==First round==
