"I can't play at 100 percent if that stuff happens - and then you expect me not to be angry", Kyrgios told Lahyani.
The Spaniard won his 75th career ATP crown and his 12th straight match in style, downing the Aussie 6-2 6-1 in brutal fashion. His first-serve percentage mostly languished under the 50 per cent mark.
Kyrgios offered Nadal eight break points in the first set with Nadal taking two service breaks.
Kyrgios didn't make it onto the board in the second set until he was serving with Nadal already leading 5-0.
The first four or five games were hotly contested and of sublime quality, but Nadal's returning, which was vastly better than it was in a loss to Kyrgios this summer in Cincinnati, and clutch serving wore down Kyrgios, who also let a bad call in the first game fester in his mind.
Writing for the playersvoice.com.au website, Kyrgios also called the final "a disappointing end to an otherwise good week".More news: Wow! These Google earphones help you speak another language instantly
The 26-year-old Halep had the superior mobility - Garcia had her right thigh strapped - but the French player was making the better shots. "She deserved to win today".
The second set was even more competitive and the attritional seventh game turned out to be a turning point. "This game was definitely very important".
Garcia is in the form of her life and edged out the Romanian second seed 6-4, 7-6 (7/3) to add the China Open to the Wuhan Open title she lifted last weekend. "It went so fast". In that 2014 fourth-round encounter at Wimbledon, the then 144th-ranked Kyrgios emerged a four-set victor.
Nick Kyrgios lost control of his emotions during the China Open final against Rafael Nadal, in which he received a point penalty following a series of verbal disagreements with the umpire. First thing, the tournament is bigger than 2005.
Despite Kyrgios' meltdown, 16-time Grand Slam champion Nadal has no doubts about the Australian player's talent as he said that he was baffled by some of his tactics.
Nadal leads Kyrgios 3-2 in career meetings, and 2-1 this season.
