The sweet yellow fruit is a contentious matter regionally, with both countries proclaiming it a national treasure and fighting over whose specimens are superior.
Economically, at least, mango exports are one area where Pakistan appears to have a slight edge.
According to respective official figures, Pakistan last year exported around 100,000 tonnes for a revenue of USD 48.6 million over India's 56,000 tonnes for USD 44.6 million.
But a European Union (EU) ban on India's prized Alphonsos, known as the "King of Fruits", has presented Pakistan with a chance to widen the gap.
The embargo came into force on May 1 after many shipments were found to contain fruit flies and also affected four types of vegetable.
For Raja Ijaz Ahmed Noon, parliamentary secretary for Pakistan's breadbasket Punjab province, improving farming standards and learning where India went wrong is critical to cashing in.
"We are taking this development as positive. We are trying to learn from the mistake which India has made," he said.
Noon was speaking after a seminar of 50 landowner-farmers at a fruit-farm 40 kilometres north-east of the central city of Multan to learn new methods of protecting mangoes from hazardous insects.
"We have a potential to export 40 per cent of our total production of mangoes and this year we will try to improve our exports up to 16 per cent," he told AFP.
Syed Ismat Hussain, a senior pest control official, said his department was visiting farms and orchards to spread the word about the lucrative profits available if Pakistan can continue to meet EU standards.
"Fruit fly hasn't only affected India but has threatened our orchards also. So we have devised simple but scientific methods to control it," he said.
Experts are busy hanging plastic bowls on mango trees that are laced with chemicals that mimic female-fly pheromones to attract males.
