The War Elephants are currently top of the group after opening their campaign with a 2-1 win over Philippines on Saturday, but the real surprise came earlier in the day when Myanmar held 2008 champions to a 1-1 draw.
Thailand head into Tuesday's clash aware that three points would seal their progress to the semi-finals but despite coming up against one of the perceived weaker sides in the tournament, Panupong insists his team-mates cannot take things for granted in their encounter at the Rajamangala Stadium.
"In the first game against Vietnam, they [Myanmar] were very strong," he told ESPNSTAR.com.
"They have two very good strikers and are also strong down the right side, so we will need to concentrate tomorrow [Tuesday]."
The Muangthong United centre-back also revealed it was important his side got off to a winning start against the Azkals at the weekend, especially considering they drew 2-2 against Laos in their opening match of the 2010 edition and were ultimately eliminated at the group stage.
Furthermore, he spoke of his belief that his side would be able to book their place in the last four against Myanmar, and insisted it was only the first step of a bigger target - winning Southeast Asia's premier international tournament.
"Sure, I'm very happy we got off to a win," Panupong added. "We had a really bad start two years ago, which is why I'm really happy to win the first game.
"I believe we have what it takes to win tomorrow's [Tuesday's] game, but we should be looking to win every game.
"We are looking to bring the Suzuki Cup back to Thailand."
Thailand's hopes of picking up three points on Tuesday is however likely to be hampered by an injury cloud over influential playmaker Datsakorn Thonglao, who sat out most of Tuesday's training.
In his absence, Osotspa Saraburi midfielder Apipoo Suntornpanavej trained with Winfried Schafer's probable starting XI but Panupong insists his club skipper could still play a part against the White Angels.
"I think [whether Datsakorn plays is] 50-50 at the moment."
Thailand, along with Singapore, hold the record for most Suzuki Cup titles following their triumphs in 1996, 2000 and 2002, but it has been ten years now since they last tasted regional glory.
