Summary

Internationale Schiedsgerichtsbarkeit, Beschwerde gegen den Teilschiedsspruch (Partial Award on Costs and Order) des Schiedsgerichts mit Sitz in Zürich vom 27. November 2020 (600519/2018).

Sachverhalt:

A.

A.a. Am 10. Mai 2018 leitete die B.________ L.P. (Klägerin, Beschwerdegegnerin) mit Sitz in U.________ bei der Swiss Chambers' Arbitration Institution (SCAI) ein Schiedsverfahren gegen die Rechtsvorgängerin der A.________ AG, V.________ (Beklagte, Beschwerdeführerin) ein.

Das Schiedsverfahren betrifft die Erfüllung eines Kaufvertrags ("Sale and Purchase Agreement") vom 3. Oktober 2013 und steht im Zusammenhang mit einem Schiedsentscheid vom 3. November 2017, der im Rahmen eines vorangehenden Schiedsverfahrens (600368/2014) erging ("Previous Award"). Es geht insbesondere um die Frage, ob die Klägerin wirksam vom Kaufvertrag zurückgetreten ist.

Der Abschluss des Sale and Purchase Agreement vom 3. Oktober 2013 beruht seinerseits auf der als "3-Way-Agreement" bezeichneten Vereinbarung, die in Artikel 7.3 die folgende Schiedsvereinbarung enthält, an welche die Parteien unbestrittenermassen gebunden sind:

"The parties hereto agree for them and their successors in title that any suit action or proceedings and settlement of any disputes which may arise out of or in connection with this agreement shall be exclusively and finally settled to the exclusion of the ordinary courts by arbitration under the Swiss Rules of International Arbitration of the Swiss Chambers of Commerce ('Swiss Rules') in force on the date when the Notice of Arbitration is submitted in accordance with these Rules by three arbitrators. The language to be used in the arbitral proceedings shall be English. Place of jurisdiction shall be Zurich."
