Evergreen seamer Peter Siddle will return to Essex in Division One after a stellar county stint last summer.
Siddle starred with 37 wickets from just seven matches showcasing his experience with the English-made Dukes ball and also played six matches for the Eagles in the Vitality Blast T20 competition.
Strikers internationals Colin Ingram and Rashid Khan will also take their talent to the UK’s limited-overs competitions.
Ingram will continue as captain of Glamorgan’s T20 Vitality Blast team and will also feature in the Royal London One-Day Cup.
The 2016 T20 Vitality Blast Player of the Tournament, Ingram was Glamorgan’s leading T20 runscorer last summer with 430 runs and three half-centuries from 11 matches.
Afghanistan leg-spinner Rashid Khan has signed for a second Vitality Blast campaign with the Sussex Sharks under Strikers coach Jason Gillespie.
Rashid claimed 17 wickets in 11 matches, including best figures of 3/9, in his maiden county campaign last summer.
Ingram and Rashid are currently playing in the Indian Premier League with Dehli Capitals and Sunrisers Hyderabad respectively.
Several other Strikers, including bastmen Jake Weatherald and Jake Lehmann, are also tipped to play club cricket at different stages of the UK summer.
First-class cricket kicks off England’s domestic season with the first round of the Specsavers County Championship from Friday, 5 April.
The Royal London One-Day Cup follows from Wednesday, 17 April and the Vitality Blast T20 competition begins on Thursday, 18 July.
