PN is looking for future ships in 4K+ ton class, 054 is one of the contenders along with German and other European ships. Sales are based on soft loans, either European or chinese, so payment is spread out over 10 odd years.
If Chinese are reluctent to sell 054, its not a loss for PN as European are very keen to sell as a package deal along with Subs ( more then likely the German U-boats, not French.) Then again the ship PN selects will have to meet its needs, so will 054 series will fit that requirement ? we should know perhaps very soon, and perhaps a similar package deal as European are offering shipd/subs and other items.
