Bahrain, meanwhile, were made to work hard by hosts Chinese Taipei before securing a 1-0 win.
Nepal 1-4 Cambodia
Cambodia exerted their dominance on the game early on, showing their prowess from corner kicks.
Vreak Phan headed in the opener in the third minute before Phoeuk Thatthai capitalised on Nepal’s failure to clear the danger to slam home their second four minutes later.
Nepal, however, recovered to not only stem the tide but also pull a goal back in the third minute of first half added time when Samir Tamang’s diving header powered home Niraj Karki’s cross.
It took 16 minutes into the second half for Cambodia to restore their two-goal lead when Mean Chanrith’s attempt from outside the box was inadvertently punched into his own net by Nepal goalkeeper Jiyarat Shekh.
As Nepal pushed more players forward, they left gaps at the back with Eav Sovannara adding another in the 83rd minute to seal the win for Cambodia, who play Uzbekistan next on Monday. Nepal will meet hosts Chinese Taipei on the same day.
Chinese Taipei 0-1 Bahrain
A continuous heavy downpour at Fu Jen University Stadium forced Chinese Taipei and Bahrain to adapt their game to trying conditions.
The first half saw little created with Chinese Taipei going the closest three minutes before the interval when Ahmeed Albari needed two attempts before clearing from under his crossbar after a Cheng Kai-Yi header.
Bahrain enjoyed more sustained possession in the second half, which led to them being awarded a penalty in the 65th minute after Ahmed Alshaikhani was bundled over by Kao Kuan-Yu, however, Alshaikhani missed the ensuing spot-kick.
The hosts would go close next, Yang Chen-Ying was sent through on goal but saw his shot blocked by a last-ditch challenge from Rashid Mejairan in the 70th minute.
Bahrain would not be denied as they found the winner with 10 minutes left to play after substitute Khaled Alkhalaf produced a low shot from distance that found the bottom corner, beating Chen Hsuan-Ting.
