Sunday's match could attract a worldwide television audience of more than a billion viewers.
Arthur said the focus now shifts to 2019 World Cup.
Widely written off after an abject display in their opening group match against the same opponents, the lowest-ranked team going into the tournament suddenly rediscovered their mojo.
Amir, who missed Pakistan's eight-wicket semi-final win over England with a back spasm, finished with three wickets for 16 runs in six overs. India won by 38 runs.
"Furthermore, the terrorists can not win and cricket must not give up on Pakistan".
Fakhar makes a confident 31 on ODI debut and Pakistan are well ahead of where they need to be, at 119 for three off 27 overs, when rain sees them win under the Duckworth/Lewis rule. Miandad anticipated a yorker so stood in front of the crease. In between the two lead spinners, they were hit for 12 boundaries and five sixes.
"We have got two years until 2019". Harbhajan sent the penultimate ball sailing over midwicket and India into the final.
Pakistan: Sarfraz Ahmed (captain and wicket-keeper), Ahmed Shehzad, Azhar Ali, Babar Azam, Mohammad Hafeez, Shoaib Malik, Hasan Ali, Mohammad Amir, Rumman Raees, Junaid Khan, Imad Wasim, Fahim Ashraf, Shadab Khan, Fakhar Zaman, Haris Sohail.
India was asked to produce the highest successful run chase in Trophy history, and had the weapons to do it. In the process, Pakistan crossed the 300 run mark with Hafeez slamming a huge six over deep square leg in the 46th over off pacer Kumar.
Even Golden Bat victor Shikhar Dhawan couldn't resist Amir's persistent accuracy, edging through outside off-stump, and when teenage spinner Shadab Khan successfully convinced Sarfraz Ahmed to review a "not out" lbw decision against Yuvraj Singh India's hopes were fading fast at 54-4.
"The turnaround has been magnificent", Kohli said. You talk about our players not playing at home but also the fans not identifying with heroes because they just don't see worldwide cricket. These weren't strokes played on the merit of the ball, they were calculated risks, even offering India a way back in if he failed.
He trapped Rohit Sharma lbw for nought with a swinging delivery and removed India talisman Virat Kohli with another fine ball which the captain could only edge to point for five. We didn't take them lightly.
"They outplayed us, they were more intense and passionate on the day", he said.
Pakistani players celebrate after winning the Champions Trophy at Oval, London, June 18, 2017. Without such moments of incompetence in what was otherwise a spectacular allround performance, there is no chance we could plausibly accept that this is the same side that lost their opening match to India by 124 runs. After the India game, we came back superbly.
India, on the other side have looked a balanced side with both their batting and bowling departments having managed to click throughout the tournament. "This is gone. If we play good cricket, definitely we will win this tournament".
